'mac80211_hwsim: Fix tracking of beaconing for multi-vif' introduced an iteration of active interfaces into the bss_info_changed handler. However, it used a wrong type of iteration and could result in a dead lock since iflist_mtx can already be held. Fix this by using the atomic version of the iteration function.
