Revert "wireless: Support of IFLA_INFO_KIND rtnl attribute"

This reverts commit ba1debdfed974f25aa598c283567878657b292ee.

Oliver reported that it breaks network-manager, for some reason with
this patch NM decides that the device isn't wireless but "generic"
(ethernet), sees no carrier (as expected with wifi) and fails to do
anything else with it.

Revert this to unbreak userspace.

Emmanuel Grumbach [Sun, 18 Jan 2015 19:39:30 +0000 (21:39 +0200)]
iwlwifi: mvm: abort scheduled scan upon RFKILL

When we have an active scheduled scan, and the RFKILL
interrupt kicks in, the stack will cancel the scheduled
scan as part of the down flow. But cancelling scheduled
scan usually implies sending a command to the firwmare
which has been killed as part of the RFKILL interrupt
handling.
Because of that, we returned an error to mac80211 when
it asked to stop the scheduled scan and didn't notify the
end of the scheduled scan. Besides a fat warning, this led
to a situation in which cfg80211 would refuse any new scan
request.

To disentangle this, fake that the scheduled scan has been
stopped without sending the command to the firwmare, return
0 after having properly let cfg80211 know that the scan
has been cancelled.

This is basically the same as:

    This code existed but not for all the different FW APIs
    we support.
    Fix this.

but for the scheduled scan case.

cfg80211: fix checking nl80211_send_station() return value

The return value from nl80211_send_station() is the length of the
skb, or a negative error, so abort sending the message only when
the return value was negative.

This fixes the ibss_rsn wpa_supplicant test case.
