mac80211: Do not send rc updates to driver before it's initialized station.
This prevents a race condition where the driver may receive updates before it's
fininished initialzing.
b/22846486
See upstream discussion at:
http://comments.gmane.org/gmane.linux.kernel.wireless.general/141276.
To reproduce, I added udelay(1000) in sta_info_insert_finish() before calling
sta_info_insert_drv_state(). Then if I run two scripts below on the client,
I can reproduce in seconds without the patch. With the patch it no longer
fails.
while :; do
iw wlan0 connect <SSID>
sleep 0.1
iw wlan0 disconnect
sleep 0.1
done
while :; do
iw dev wlan0 set power_save off
iw dev wlan0 set power_save on
done
