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.
