Remove the ScsiResult macro and open code it on all call sites.

This will make subsequent refactoring in this area easier.

Please consider to remove the SCSI_STATUS_GOOD constant since it is
non-standard and since it used by the bfa driver only. Additionally, since
SCSI_STATUS_GOOD == 0, please leave out "| SCSI_STATUS_GOOD".

Thanks,

Bart.

Can we agree on using SAM_STAT_GOOD here? I really don't want to leave
out the trailing "| 0" parts in this stage of the refactoring yet. I'm
still undecided if I don't want a set_scsi_cmnd_status(cmnd, foo, bar,
baz, frob); function in an intermediate step.
