scsi: hisi_sas: Fix normally completed I/O analysed as failed
The PIO read command has no response frame and the struct iu[1024] won't be
filled. I/Os which are normally completed will be treated as failed in
sas_ata_task_done() when iu contains abnormal dirty data.
Consequently ending_fis should not be filled by iu when the response frame
hasn't been written to memory.
Fixes: d380f55503ed ("scsi: hisi_sas: Don't bother clearing status buffer IU in task prep")
