find_vqs operation starting at arbitrary index
...can be made to work by passing the 'start_index' value as
was done earlier for find_vq, but I doubt something like the following
will work. The MSI vectors might need some changing as well.
If this indeed is the right way to do it, I can add a
virtio_find_vqs helper along similar lines as virtio_find_single_vq and
pass '0' as the start index to the ->find_vqs operation.
Or is there another way to do it?
