Minhong He c0fd47726c ipv4: nexthop: handle errors in nexthop_init() ...

nexthop_init() ignores errors from register_pernet_subsys() and
register_netdevice_notifier(), so a partial initialization can appear
successful.

Check those steps and unwind prior registrations on failure.

Do not check rtnl_register_many(): for built-in code it panics on
failure, so the call cannot return an error to nexthop_init().
