[vhost] sending data to guest, async

1. Is there a method to send data to the guest from vhost with the
current API?
2. Is there a way I could do this asynchronously? From what I see from
the vhost-net and vhost-scsi model, data from the quest is mapped onto
vq->iov. So I can't process data out of order and then send something
resulting from this, because on vq->iov there would be something else
mapped (another job mapped).
