Xingui Yang 1e5eac0022 scsi: hisi_sas: Fix normally completed I/O analysed as failed
[ Upstream commit f5393a5602cacfda2014e0ff8220e5a7564e7cd1 ]

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: d380f55503 ("scsi: hisi_sas: Don't bother clearing status buffer IU in task prep")
