this will work due to INIT_LIST_HEAD with circles list to itself and a
del operation will work.

By the way, I think that we can in the case of undefined CONFIG_NET_NS
reduce register to calling ->init method and unregister to calling
->exit method.

This is a correct thing at least for now and will be welcomed by the all
embedded/etc people.
