[MAC80211]: add sta_notify callback
This patch adds sta_notify callback and removes sta_table_notification
which was not used by any driver.
sta_notify() is essential for drivers that keeps notion of station
internally and need to be notified about removal or addition of a station
to the (I)BSS or assocation to an AP.
This version adds interface id to the parameter list
as suggested by Johannes Berg
