rtnetlink: Use register_pernet_subsys() in rtnl_net_debug_init().
rtnl_net_debug_init() registers rtnl_net_debug_net_ops by
register_pernet_device() but calls unregister_pernet_subsys()
in case register_netdevice_notifier() fails.
It corrupts pernet_list because first_device is updated in
register_pernet_device() but not unregister_pernet_subsys().
Let's fix it by calling register_pernet_subsys() instead.
The _subsys() one fits better for the use case because it keeps
the notifier alive until default_device_exit_net(), giving it
more chance to test NETDEV_UNREGISTER.
Fixes: 03fa53485659 ("rtnetlink: Add ASSERT_RTNL_NET() placeholder for netdev notifier.")
