cdrom_id: Do not ignore errors from scsi_cmd_run()
scsi_cmd_run() can return positive error messages if we have CHECK_CONDITION
set and get the error code from the SCSI command result. So check the result
for non-zero, not for being negative.
This should fix another cause for "phantom" media in empty CD-ROM drives.
Thanks to Mike Brudevold <mike@brudevold.com> for spotting this!
