if_loop doesn't need to keep the list of lo(4) interfaces. Today
a private softc list is needed neither for tracking clones in general
nor for destroying all clones before the module unload -- if_clone
takes care of all that. (Note that some other interface drivers do
need a softc list to be able to scan it for their private purposes.)
