Add default in switch (#8065)

Summary:
switch may not cover all branch in `db/c.cc`:

```c++
void rocksdb_options_set_access_hint_on_compaction_start(
    rocksdb_options_t* opt, int v) {
  switch(v) {
    case 0:
      opt->rep.access_hint_on_compaction_start =
          ROCKSDB_NAMESPACE::Options::NONE;
      break;
    case 1:
      opt->rep.access_hint_on_compaction_start =
          ROCKSDB_NAMESPACE::Options::NORMAL;
      break;
    case 2:
      opt->rep.access_hint_on_compaction_start =
          ROCKSDB_NAMESPACE::Options::SEQUENTIAL;
      break;
    case 3:
      opt->rep.access_hint_on_compaction_start =
          ROCKSDB_NAMESPACE::Options::WILLNEED;
      break;
  }
}
```
