scsi: hisi_sas: add TMF success check
When a tmf is issued, various response codes can be returned from the
target. For a query tmf the response may be TMF_RESP_FUNC_COMPLETE or
TMF_RESP_FUNC_SUCC. Add a condition for TMF_RESP_FUNC_SUCC to
hisi_sas_exec_internal_tmf_task(). This affects query tmf, as the
result is success the returned value was for failure.
