William A. Kennington III d084245e74 iproute: Fix regressions introduced in 3.16.0
3.16.0 introduced a regression where vlan and veth devices could not be
created due to a check in the code for existing devices. This applies
the upstream patch which fixes the issue.

Additionally, this corrects the nixos network-interfaces task which now
needs to specify the name parameter when adding links.

Subject: 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.
