So it can happen that the SCSI error handler tries to abort a SCSI command after it has been reset by srp_rport_reconnect(). Tell the SCSI error handler that such commands have finished and that it is not necessary to continue its recovery strategy for commands that have been reset by srp_rport_reconnect().
