It should not have been part of that series.  I am dropping the other
two patches and will resend this as a standalone change.

Also, the previous version was incomplete: vhost_virtqueue_mask() is
void today, so simply checking its return value was wrong.  The new
patch makes it return the errno from vhost_set_vring_call().  On
failure in vhost_virtqueue_start(), we jump to the existing fail path,
which unmaps the vring and returns the error so device start fails
instead of continuing with a half-configured queue.

Thanks,
