vhost-scsi: Clarify vhost_virtqueue_mask argument

vhost_virtqueue_mask takes an "absolute" virtqueue index, while the
code looks like it's passing an index that is relative to
s->dev.vq_index.  In reality, s->dev.vq_index is always zero, so
this patch does not make any difference, but the code is clearer.
