Update validation cases for new HVAC rules

I see this error
```
LLNL_Enclosure/Current_Results/LLNL_64.err:ERROR(yyy): Ductnode with one duct needs either GEOM or VENT_ID. Ductnode ID:INLET A, HVAC line number:    1 (CHID: LLNL_64)
```
on several cases for `LLNL_Enclosure`. This error needs a code rather than `yyy` and could you look to see what is not correct in these files.
