wifi: mt76: mt7996: hold dev->mutex in remove_interface teardown

Browse source

mt7996_remove_interface() destroys the remaining vif links, clearing
omac_mask, vif_mask and mld_idx_mask, with only the wiphy mutex held.
Those masks are modified under dev->mutex everywhere else, so the
unlocked clears can race the scan-link teardown and the reset work
and lose updates.

Take dev->mutex around the link destroy loop, matching
mt7996_add_interface() and mt7915_remove_interface(). The mutex is
released before mt76_vif_cleanup(), which aborts a pending scan and
takes the mutex itself.
