Review comment:
It won't affect the correctness. The `latestCompletedInstant` is used to
filter file slice. Considering a compaction only case, without including the
completed compaction instant, we will end up reading 'old version' file slice
(i.e., base file + log) rather than the compacted one (i.e., only base file,
which has better performance).
