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.
