3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eliad Peller <el...@wizery.com>
commit 3d2abdfdf14f4d6decc2023708211e19b096f4ca upstream.
ifmgd->bssid wasn't cleared properly in some
auth/assoc failure cases, causing mac80211 and
the low-level driver to go out of sync.
Clear ifmgd->bssid on failure, and notify the driver.
