hv_netvsc: set master device

[ Upstream commit 97f3efb64323beb0690576e9d74e94998ad6e82a ]

The hyper-v transparent bonding should have used master_dev_link.
The netvsc device should look like a master bond device not
like the upper side of a tunnel.

This makes the semantics the same so that userspace applications
looking at network devices see the correct master relationshipship.
