[PATCH net-next v3 18/32] net: Convert pernet_subsys ops, registered via net_dev_init()

There are:
1)dev_proc_ops and dev_mc_net_ops, which create and destroy
pernet proc file and not interesting for another net namespaces;
2)netdev_net_ops, which creates pernet hashes, which are not
touched by another pernet_operations.

So, make them async.
