[PATCH v2 net 2/3] virtio_net: fix adding vids on big-endian

["Michael S. Tsirkin" <mst@redhat.com>]

Programming vids (adding or removing them) still passes
guest-endian values in the DMA buffer. That's wrong
if guest is big-endian and when virtio 1 is enabled.

Note: this is on top of a previous patch:
	virtio_net: split out ctrl buffer

Fixes: 9465a7a6f ("virtio_net: enable v1.0 support")
