Review Comment:
This seems to happen in two cases:
1. The tablet has no rowset.
2. The version of max version rowset no longer exists in the tablet.
In fact, I did not carefully analyze why it occurs. Because other
`tablet->rowset_with_max_version()` all compare whether the return value is
null, so I also compare here :)
