mac80211: add sta_state callback
(based on Eliad's patch) Add a callback to notify the low-level driver whenever the state of a station changes. The driver is only notified when the station is actually in the mac80211 hash table, not for pre-insert state transitions. To allow the driver to replace sta_add/remove calls with this, call extra transitions with the NOTEXIST state. This callback can fail, so we need to be careful in handling it when a station is inserted, particularly in the IBSS case where we still keep the station entry around for mac80211 purposes.
