mac80211: annotate station rcu dereferences
The new RCU lockdep support warns about these
in some contexts -- make it aware of the locks
used to protect all this. Different locks are
used in different contexts which unfortunately
means we can't get perfect checking.
Also remove rcu_dereference() from two places
that don't actually dereference the pointers.
