wifi: mt76: mt7925: fix lock inversion between dev->mutex and iflist_mtx

Browse Source 
mt7925_config() has the same inversion as mt7921_config(): it holds
dev->mutex across ieee80211_iterate_active_interfaces(), which takes
local->iflist_mtx, while mac80211 calls drv_unassign_vif_chanctx() with
iflist_mtx already held.

.config is only reached through drv_config(), which asserts the wiphy
mutex, so use ieee80211_iterate_active_interfaces_mtx() here too.
