From: Juan Quintela <quintela@redhat.com>
Two things, at this point:
* n->primary_device_id has to be set, otherwise
virtio_net_find_primary don't work. So we have a leak here.
* it has to be exactly the same that prim_dev->id because what
qdev_find_recursive() does is just compare this two values.
So remove the unneeded assignment and leaky bits.
