Subject: [PATCH RFC 15/25] net: Move netlink_net_ops to pernet_sys list

According to net/core/Makefile, net/core/af_netlink.o
core initcalls execute right after net/core/net_namespace.o.

The methods of netlink_net_ops create and destroy "netlink"
file, which are not interested for foreigh pernet_operations.
So, netlink_net_ops may safely be moved to pernet_sys list.
