libata-scsi: be tolerant of 12-byte ATAPI commands in 16-byte CDBs
Sebastian Kemper reported that issuing CD/DVD commands under libata is
not fully compatible with ide-scsi. In particular, the
GPCMD_SET_STREAMING was being rejected at the host level in some
instances.
The reason is that libata-scsi insists upon the cmd_len field exactly
matching the SCSI opcode being issued, whereas ide-scsi tolerates
12-byte commands contained within a 16-byte (cmd_len) CDB.
There doesn't seem to be a good reason for us to not be compatible
there, so here is a patch to fix libata-scsi to permit SCSI opcodes so
long as they fit within whatever size CDB is provided.
