[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.
