crimson/osd: fix the serialization of notify_reply_t.

The `LibRadosWatchNotify.WatchNotify2` was expecting
data in the very raw form:

```cpp
  std::map<std::pair<uint64_t,uint64_t>, bufferlist> reply_map;
  std::set<std::pair<uint64_t,uint64_t> > missed_map;
  auto reply_p = reply.cbegin();
  decode(reply_map, reply_p);
  decode(missed_map, reply_p);
```

while the serialization of `notify_reply_t` was appending
extra preamable with versioning data.

This was the root cause of the following problem:
