    net/virtio-user: get max number of queue pairs from device



    When supported by the backend (only vDPA for now), this
    patch gets the maximum number of queue pairs supported by
    the device by querying it in its config space.



    This is required for adding backend control queue support,
    as is index equals the maximum number of queues supported
    by the device as described by the Virtio specification.
