The REPORT_SUPPORTED_OPERATION_CODES command allows checking for support
of commands that have the same opcode but different service actions,
such as READ 32 and WRITE 32. However, the current implementation of
scsi_report_opcode() only allows checking an operation code without a
service action differentiation.

Add the "sa" argument to scsi_report_opcode() to allow passing a service
action. If a non-zero service action is specified, the reporting
options field value is set to 3 to have the service action field taken
into account by the device. If no service action field is specified
(zero), the reporting options field is set to 1 as before.
