The Quantum GoVault SATAPI removable disk device returns ATA_ERR in
response to a REPORT LUNS packet. If this happens to an ATAPI device
that is attached to a SAS controller (this is the case with sas_ata),
the device does not load because SCSI won't touch a "SCSI device"
that won't report its LUNs. Since most ATAPI devices don't support
multiple LUNs anyway, we might as well fake a response like we do for
ATA devices.
