scsi: uas: Drop DID_TARGET_FAILURE use

Browse Source 
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 entering SCSI error handling.

It looks like the driver wanted a hard failure so this swaps it with
DID_BAD_TARGET which gives us that behavior. 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).
