We used to do alloc_netdev and register_netdev at the same time in
iwm_if_alloc. But some bus related structures will only be initialized
after iwm_priv is allocated. This caused a race condition that the
netdev might be registered earlier. The patch adds iwm_if_add and
iwm_if_remove so that the bus layer could register the device after
all initialization is done.
