scsi: hisi_sas: Handle the NCQ error returned by D2H frame

We find that some disks use D2H frame instead of SDB frame to return NCQ
error. Currently, only the I/O corresponding to the D2H frame is processed
in this scenario, which does not meet the processing requirements of the
NCQ error scenario.  So we set dev_status to HISI_SAS_DEV_NCQ_ERR and abort
all I/Os of the disk in this scenario.
