mac80211: don't send null data packet when not associated
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.
