Subject[PATCH RFC 08/25] net: Move proc_net_ns_ops to pernet_sys list
This patch starts to convert pernet_subsys, registered
from before initcalls.

Since proc_net_ns_ops is registered pernet_subsys,
made from:


and there is no a pernet_subsys, which is registered
earlier, we start from it.

register pernet net->proc_net and ->proc_net_stat, and
constructors and destructors of another pernet_operations
are not interested in foreign net's proc_net and proc_net_stat.
Proc filesystem privitives are synchronized on proc_subdir_lock.

So, it's safe to move proc_net_ns_ops to pernet_sys list
and execute its methods in parallel with another pernet
