libata: add support for ATA_16 on ATAPI
Add support for issuing ATA_16 passthru commands to ATAPI devices
managed by libata. It requires the previous CDB length fix patch.
A boot/module parameter, "atapi_passthru16=0" can be used to globally
disable this feature, if ever desired.
tj: restructured __ata_scsi_queuecmd() according to Jeff's suggestion.
