mac80211: make ieee80211_find_sta per virtual interface
Since we have a TODO item to make all station
management dependent on virtual interfaces, I
figured I'd start with pushing such a change
to drivers before more drivers start using the
ieee80211_find_sta() API with a hw pointer and
cause us grief later on.
For now continue exporting the old API in form
of ieee80211_find_sta_by_hw(), but discourage
its use strongly.
