Single fix for libata: older devices don't support command duration limits (CDL) and some don't support report opcodes, meaning there's no way to tell if they support the command or not. Reduce the problems of incorrectly using CDL commands on older devices by checking SCSI spec compliance at SPC-5 (the spec which introduced the command) before turning on CDL.
