DID_TARGET_FAILURE is internal to the SCSI layer. Drivers must not use it because: 1. It's not propagated upwards, so SG IO/passthrough users will not see an error and think a command was successful. 2. There is no handling for them in scsi_decide_disposition so it results in the scsi eh running. This has qla2xxx use DID_NO_CONNECT because it looks like we hit this error when we can't find a port. It will give us the same hard error behavior and it seems to match the error where we can't find the endpoint.
