plex(cgns): Disallow writing already-written solution
This avoids errors like:
```

where a solution was written on timestep 26, the next timestep failed,
then `ts_monitor_solution` attempts to write the same solution to the
CGNS file, but the CGNS library complains that a solution with the same
name already exists.
