mac80211: acquire sta_lock for station suspend/resume

To avoid concurrent manipulations of the sta list (which shouldn't
be possible at this point, but anyway) we need to hold the sta_lock
around iterating the list.

At the same time, we do not need to iterate the list at all if
the driver doesn't want to be notified.
