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.

It looks like the driver wanted a hard failure so this swaps it with
DID_BAD_TARGET which gives us that behavior and the error looks like it's
for a case where the target did not support a TMF we wanted to use (maybe
not a bad target but disappointing so close enough).
