scsi: hisi_sas: Fix normally completed I/O analysed as failed

Browse source

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.
