cdrom_id: Fall back to CDROM_DRIVE_STATUS if all MMC commands fail
Reportedly, some "when I'm grown up I want to be a CD drive" fake USB CD sticks
like the IronKey neither support the SCSI "GET CONFIGURATION" nor the older
(pre-MMC2) "READ DISC INFORMATION" command. In that case, check if
cd_media_compat() detected that there is a disc present, and assume that we
have a CD-ROM medium.
