scsi: xen: Drop use of internal host codes
The error codes:
- DID_TARGET_FAILURE
- DID_NEXUS_FAILURE
- DID_ALLOC_FAILURE
- DID_MEDIUM_ERROR
are internal to the SCSI layer. Drivers must not use them because:
1. They are not propagated upwards, so SG IO/passthrough users will not
see an error and think a command was successful.
xen-scsiback will never see this error and should not try to send it.
2. There is no handling for them in scsi_decide_disposition() so if
xen-scsifront were to return the error to the SCSI midlayer then it
kicks off the error handler which is definitely not what we want.
Remove the use from xen-scsifront/back.
