Johannes Berg f7c65594f7 mac80211: fix ieee80211_find_sta[_by_hw]
Both of these functions can currently return
a station pointer that, to the driver, is
invalid (in IBSS mode only) because adding
the station failed. Check for that, and also
make ieee80211_find_sta() properly use the
per interface station search.
