rtlwifi: Initialize rate_init member of struct rate_control_ops

This partially reverts commit 44ba973699b831414c3f8eef68ee5a7fe1208a05.

rate_control_rate_init assumes the rate_init member of
struct rate_control_ops is not NULL therefore not initializing it leads to
an oops as soon the driver succesfully associates to an AP.

The removal of rate_update from 44ba973699b831414c3f8eef68ee5a7fe1208a05
is ok because rate_update is checked for NULL before being
called.

iwlwifi: mvm: don't wait for session protection to start

Now that mac80211 no longer starts the auth/assoc
timeouts when it transmits the frame, but only when
the frame status arrives, we no longer need to wait
for the session protection time event to start, we
can schedule it and enqueue the auth/assoc frame
right away. This reduces the amount of time we block
mac80211's workqueue.

Also, since now we no longer need different behavior
for session protection and P2P time events, refactor
the code to have just a common implementation.

mac80211: Add flushes before going off-channel

We've got a couple of races when enabling powersave with an AP for
off-channel operation. The first is fairly simple. If we go off-channel
before the nullfunc frame to enable PS is transmitted then it may not be
received by the AP. Add a flush after enabling off-channel PS to prevent
this from happening.

The second race is a bit more subtle. If the driver supports QoS and has
frames queued when the nullfunc frame is queued, those frames may get
transmitted after the nullfunc frame. If PM is not set then the AP is
being told that we've exited PS before we go off-channel and may try to
deliver frames. To prevent this, add a flush after stopping the queues
but before passing the nullfunc frame to the driver.

mac80211: Fix tx queue handling during scans

Scans currently work by stopping the netdev tx queues but leaving the
mac80211 queues active. This stops the flow of incoming packets while
still allowing mac80211 to transmit nullfunc and probe request frames to
facilitate scanning. However, the driver may try to wake the mac80211
queues while in this state, which will also wake the netdev queues.

To prevent this, add a new queue stop reason,
IEEE80211_QUEUE_STOP_REASON_OFFCHANNEL, to be used when stopping the tx
queues for off-channel operation. This prevents the netdev queues from
waking when a driver wakes the mac80211 queues.

This also stops all frames from being transmitted, even those meant to
be sent off-channel. Add a new tx control flag,
IEEE80211_TX_CTL_OFFCHAN_TX_OK, which allows frames to be transmitted
when the queues are stopped only for the off-channel stop reason. Update
all locations transmitting off-channel frames to use this flag.

NET: ath5k, check ath5k_eeprom_mode_from_channel retval

It can, if invalid argument given, return a negative value. In that
case we would access arrays out-of-bounds and such. Check the value
and yell loudly if that happened as it would be a bug in the
implementation. (Instead of silently corrupting memory.)

brcmfmac: fix problem connecting to AP without security

The bcm43236 device showed having an issue connection to an AP without
security when auth_type was set to automatic. For this particular device
a workaround is made by selecting open-system. This problem does not
occur when using wpa_supplicant as it will not use auth type automatic.
