scsi: hisi_sas: Modify v3 HW ATA completion process when SATA disk is in error status
driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5Q63H CVE: NA ------------------------------------- When an NCQ error occurs, SAS controller will abnormally complete the I/Os that newly delivered to disk, and bit8 in CQ dw3 will be set to 1 to indicate current SATA disk is in error status. The current processing flow is set ts->stat to SAS_OPEN_REJECT and then sas_ata_task_done() will set fis stat to ATA_ERR. After analyzed by ata_eh_analyze_tf(), err_mask will set to AC_ERR_HSM. If media error occurs for four times within 10 minutes and the chip rejects new I/Os for four times, NCQ will be disabled due to excessive errors. However, if media error occurs multiple times, the NCQ mode shouldn't be disabled. Therefore, use sas_task_abort() to handle abnormally completed I/Os when SATA disk is in error status.
