net: Convert ctnetlink_net_ops
These pernet_operations register and unregister two conntrack notifiers, and they seem to be safe to be executed in parallel. General/not related to async pernet_operations JFI: ctnetlink_net_exit_batch() actions are grouped in batch, and this could look like there is synchronize_rcu() is forgotten. But there is synchronize_rcu() on module exit patch (in ctnetlink_exit()), so this batch may be reworked as simple .exit method.
