Edward Adam Davis 171cd66ffd wifi: cfg80211: fix RCU dereference in __cfg80211_bss_update
[ Upstream commit 1184950e34 ]

Replace rcu_dereference() with rcu_access_pointer() since we hold
the lock here (and aren't in an RCU critical section).

Fixes: 32af9a9e10 ("wifi: cfg80211: free beacon_ies when overridden from hidden BSS")
