That would be the minimal fix.  We'd then still need to enumerate
the allowed positive return values and check noting else is returned.

I don't like the opt in in the other version.  The SCSI return values are
the defactor API, and we need to switch NVMe to align with it ASAP
instead of keeping the broken old version around.
