disable_wal and reopen are incompatible (#13372)

Summary:
We want to disable WAL for RoWS stress tests (anand1976 made a config change to explicitly do this), but it turns out that is not compatible with `reopen` > 0.

I found this error in the logs:
```
Error: Db cannot reopen safely with disable_wal set!
```

Pull Request resolved: https://github.com/facebook/rocksdb/pull/13372

Test Plan: We should not get this error message in the RoWS stress tests.
