When there're no growing segments in the collection, L0 Compaction will
try to choose all L0 segments that hits all L1/L2 segments.
However, if there's Sealed Segment still under flushing in DataNode at
the same time L0 Compaction selects satisfied L1/L2 segments, L0
Compaction will ignore this Segment because it's not in "FlushState",
which is wrong, causing missing deletes on the Sealed Segment.
This quick solution here is to fail this L0 compaction task once
selected a Sealed segment.
