This is a prep for the next series where we will push RTNL down to rtnl_{new,del,set}link(). That means, for example, __rtnl_newlink() is always under RTNL, but rtnl_newlink() has a non-RTNL section. As a prerequisite for per-netns RTNL, we will move netns validation (and RTNL-independent validations if possible) to that section. rtnl_link_ops and rtnl_af_ops will be protected with SRCU not to depend on RTNL.
