Temporarily disable wal compression (#10108)

Summary:
Will re-enable after fixing the bug in https://github.com/facebook/rocksdb/issues/10099 and https://github.com/facebook/rocksdb/issues/10097.
Right now, the priority is https://github.com/facebook/rocksdb/issues/10087, but the bug in WAL compression prevents the mini crash test from passing.
