mac80211: disentangle iflist_mtx and chanctx_mtx
At least on iwlwifi, sometimes lockdep complains that we can
lock
chanctx_mtx -> mvm.mutex -> iflist_mtx
(due to iterate_interfaces)
and
iflist_mtx -> chanctx_mtx
Remove the latter dependency in mac80211 by using the RTNL
that we already hold in one case, and can relatively easily
achieve in the other case.
