[GENETLINK]: Relax dances with genl_lock.
The genl_unregister_family() calls the genl_unregister_mc_groups(),
which takes and releases the genl_lock and then locks and releases
this lock itself.
Relax this behavior, all the more so the genl_unregister_mc_groups()
is called from genl_unregister_family() only.
