ieee1394: sbp2: better handling of transport errors
If the target signals a transport failure via status block, complete the request with DID_BUSY to indicate to the SCSI subsystem that the command may succeed when retried. Also log diagnostic information if the status block shows a transport related problem. It may point to hardware faults. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
