GSO values are not correctly set for peer and dev. When creating
the veth link, GSO attributes are set for peer device, propagate
these values from peer to dev.

Seems this patch won't be necessary after all. Parameter order in
iproute2 util will be changed to set GSO on first dev device (not
on the peer), making current code right: cloning from dev to peer.
