hisi_sas: fix v1 hw check for slot error
Completion header bit CMPLT_HDR_RSPNS_XFRD flags whether the response
frame is received into host memory, and not whether the response frame
has an error. As such, change the decision on whether a slot has an
error. Also redundant check on CMPLT_HDR_CMD_CMPLT_MSK is removed.
