ata: libata-scsi: improve service action support in ata_scsi_report_supported_opcodes()

Browse source

ata_scsi_report_supported_opcodes() is ignoring the service action
specified in the SCSI command CDB, but the one command format must take
this field into consideration. With the reporting options field set to 1,
the REPORT SUPPORTED OPERATION CODES command must be failed if the
specified opcode to check has service actions, while reporting option 3
must match supported opcodes together with the specified service action.

Stop ignoring the service action by passing it to
ata_scsi_cmd_is_supported() and searching for commands in the
array of supported commands (ata_supported_cmds) using both the command
opcode and service action.

Introduce the helper function ata_scsi_supported_cmd_use_sa() to determine
if a particular command has service actions and use this function to fail
a REPORT SUPPORTED OPERATION CODES command if such command is specified
with reporting options 1.
