In virtio_pq_send_command() we check for a used descriptor and wait in an idle loop until it becomes used. We can't use vq->used_wrap_counter here to check for the first descriptor we made available because the ring could have wrapped. Let's use the used_wrap_counter that matches the state of the head descriptor.
