Subject: kv/memdb: fix uninitialized return of MemDB::_init().
X-Git-Tag: v16.1.0~430^2

kv/memdb: fix uninitialized return of MemDB::_init().

Without this fix GCC complains:

```
src/kv/MemDB.cc:179:10: warning: ‘r’ may be used uninitialized in this function [-Wmaybe-uninitialized]
  179 |   return r;
```
