The real checking is performed later in iplink_modify(..) func which
checks device existence if NLM_F_CREATE flag is set.

Also it fixes the case when impossible to add veth link which was
caused by 9a02651a87 (ip: check for missing dev arg when doing VF rate)
because these devices are not exist yet.

This also fixes this issue from Mehdi Abaakouk here:
http://marc.info/?l=linux-netdev&m=140912053421637

And the stuff I needed to change here:
https://gitorious.org/linux-can/can-tests/commit/578d07b0a13e0c171801cde8c048ac657373491e

Thanks for figuring out the detailed problem Vadim!

Regards,
Oliver
