migration: Add migration_incoming_transport_cleanup()
Add a helper to cleanup the transport listener. When do it, we should also null-ify the cleanup hook and the data, then it's even safe to call it multiple times. Move the socket_address_list cleanup altogether, because that's a mirror of the listener channels and only for the purpose of query-migrate. Hence when someone wants to cleanup the listener transport, it should also want to cleanup the socket list too, always. No functional change intended.
