[PATCH v2 18/31] net: Convert pernet_subsys ops, registered via net_dev_init()

[Kirill Tkhai]

There are:
1)dev_proc_ops and dev_mc_net_ops, which create and destroy
pernet proc file and not interested to another net namespaces;
2)netdev_net_ops, which creates pernet hash, which is not
touched by another pernet_operations.

So, make them async.
