This patch moves validate_linkmsg() out of do_setlink() to its callers
and deletes the early validate_linkmsg() call in __rtnl_newlink(), so
that it will not call validate_linkmsg() twice in either of the paths:
- __rtnl_newlink() -> do_setlink()
- __rtnl_newlink() -> rtnl_newlink_create() -> rtnl_create_link()
Additionally, as validate_linkmsg() is now only called with a real
dev, we can remove the NULL check for dev in validate_linkmsg().
Note that we moved validate_linkmsg() check to the places where it has
not done any changes to the dev, as Jakub suggested.
