we assumed that drivers never give us spurious deauth
frames because they filter them out based on the auth
state they keep track of. This turned out to be racy,
because userspace might deauth while the AP is also
sending a deauth frame, so the warning was removed.

However, in that case we should not tell userspace
about the AP's frame if it requested deauth "first",

by enable continuous event logging, driver check the write pointer
and log the newly added events in iwl_bg_ucode_trace() timer function.

much better understanding of the uCode behavior during runtime; it can
help to debug the uCode related issues.

Methods to enable/disable the continuous event log:
step 1: enable ucode trace timer
     "echo 1 >
/sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing"
step 2: start ftrace

step 4: disable ucode trace timer
     "echo 0 >
/sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing"

use "ucode_tracing" debugfs file to display number of event
queue wrapped when driver attempt the continuous event logging. If event
queue being wrapped more than once when driver has opportunity to log
