ata: libata-scsi: ignore reserved bits for REPORT SUPPORTED OPERATION CODES
For REPORT SUPPORTED OPERATION CODES command, the service action field is
defined as bits 0-4 in the second byte in the CDB. Bits 5-7 in the second
byte are reserved.
Only look at the service action field in the second byte when determining
if the MAINTENANCE IN opcode is a REPORT SUPPORTED OPERATION CODES command.
This matches how we only look at the service action field in the second
byte when determining if the SERVICE ACTION IN(16) opcode is a READ
CAPACITY(16) command (reserved bits 5-7 in the second byte are ignored).
Fixes: 7b2030942859 ("libata: Add support for SCT Write Same")
