    [SCSI] aic94xx: Don't eat TMF_QUERY_TASK results
    In this driver, TMF_QUERY_TASK translates to QUERY_SSP_TASK.  The
    sequencer, it seems, is perfectly happy sending us a SSP response, which
    this function promptly "converts" into TMF_RESP_FUNC_FAILED.  This leads to
    the SAS EH making bad decisions based on bad data, so we should not perform
    the conversion in this case.
