    hw/scsi: Use error_setg_file_open() for a better error message

    The error message changes from

        vhost-scsi: open vhost char device failed: REASON

    to

        Could not open '/dev/vhost-scsi': REASON

    I think the exact file name is more useful to know than the file's
    purpose.

    We could put back the "vhost-scsi: " prefix with error_prepend().  Not
    worth the bother.
