rtnetlink: allow rtnl_fill_link_netnsid() to run under RCU protection

Browse source

We want to be able to run rtnl_fill_ifinfo() under RCU protection
instead of RTNL in the future.

All rtnl_link_ops->get_link_net() methods already using dev_net()
are ready. I added READ_ONCE() annotations on others.
