The vhost work flush function was flushing the entire work queue, so there is no need for the double vhost_work_dev_flush calls in vhost_scsi_flush. And we do not need to call vhost_poll_flush for each poller because that call also ends up flushing the same work queue thread the vhost_work_dev_flush call flushed.
