mac80211: rx: avoid RCU list traversal under mutex
[ Upstream commit 253216ffb2a002a682c6f68bd3adff5b98b71de8 ]
local->sta_mtx is held in __ieee80211_check_fast_rx_iface().
No need to use list_for_each_entry_rcu() as it also requires
a cond argument to avoid false lockdep warnings when not used in
RCU read-side section (with CONFIG_PROVE_RCU_LIST).
Therefore use list_for_each_entry();
