For a sync task, the segment could be compacted during sync task. In
previous implementation, this sync task will hold only the old segment
id as KeyLock, in which case compaction on compacted to segment may run
in parallel with delta sync of this sync task.
This PR introduces sync target segment verification logic. It shall
check target segment lock it's holding beforing actually syncing logic.
If this check failed, sync task shall return`errTargetSegementNotMatch`
error and make manager re-fetch the current target segment id.
