3.5.7.2 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.berg@intel.com>
commit 20f544eea03db4b498942558b882d463ce575c3e upstream.
On resume or firmware recovery, mac80211 sends a null data packet to see if the AP is still around and hasn't disconnected us. However, it always does this even if it wasn't even connected before, leading to a warning in the new channel context code. Fix this by checking that it's associated.
