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 it in scsi_decide_disposition() so it results
    in the SCSI error handling running.

It looks like the driver wanted a hard failure so swap it with
DID_BAD_TARGET.
