cfg80211/mac80211: avoid state mishmash on deauth
commit 6863255bd0e48bc41ae5a066d5c771801e92735a upstream.
Avoid situation when we are on associate state in mac80211 and
on disassociate state in cfg80211. This can results on crash
during modules unload (like showed on this thread:
http://marc.info/?t=134373976300001&r=1&w=2) and possibly other
problems.
