Revert "scsi: hisi_sas: Modify v3 HW I/O processing when SATA_DISK_ERR bit is set and NCQ Error occurs"

driver inclusion
category: bugfix

-----------------------------

This reverts commit fc811070.

After an error occurs in the NCQ scenario, the policy similar to the ahci
driver is used to handle NCQ exceptions. The libata interface
ata_link_abort is invoked to process all I/Os on the link. Compared with
the current solution, the code modification amount is small, and the
possibility of NCQ being disabled decreases. That is, the probability of
performance deterioration is low. So revert it.
