[libvirt] [PATCH 3/3] util: Report error if vhost-scsi device file cannot be found
https://bugzilla.redhat.com/show_bug.cgi?id=1523564
If the vhost-scsi device file cannot be found, the generic error
"error: An error occurred, but the cause is unknown"
is returned. Let's add a real error message to make it clear
why the failure occurred.
