mac80211: fix monitor_sdata RCU/locking assertions
Since commit a05829a ("cfg80211: avoid holding the RTNL when calling the driver") we've not only been protecting the pointer to monitor_sdata with the RTNL, but also with the wiphy->mtx. This is relevant in a number of lockdep assertions, e.g. the one we hit in ieee80211_set_monitor_channel(). However, we're now protecting all the assignments/dereferences, even the one in interface iter, with the wiphy->mtx, so switch over the lockdep assertions to that lock.
