  From: Stefan Hajnoczi <stefanha@redhat.com>

Currently, the only way of determining a struct vhost_virtqueue's index
is to search struct virtio_net->virtqueue[] for its address.  Stash the
index in struct vhost_virtqueue so we won't have to search the array.

This new field will be used by virtio-vhost-user.
