We're not there yet, but getting closer...
These response codes are _not_ SCSI status codes that go in the
SRP_RSP's status field. They go (in the error case) in the "response
data" field, so you have to set RSPVALID and set the first four bytes of
the data[] array in the format that I mentioned before.
The status field must be zero, because the spec says: "Response data
shall not be provided in any SRP_RSP response that returns a non-zero
status code in the STATUS field".
