Backport fix for ip link add name regression that broke libvirt

Used to work in 3.14, broken in 3.16. Fix already upstream.
Libvirt does this when adding a veth pair:

  # ip link add vnet18 type veth peer name vnet19
  Error: argument "vnet18" is wrong: Unknown device

Subject: [PATCH] ip link: Remove unnecessary device checking
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.
