enhance: Refine channelCpUpdater field & test (#33083)
Avoid passing datanode around preparing datanode code directory
refactory.

Also refine unit test code for same component. The `Await` shall return
first before checking the counter number since when lock cost is heavy
(using deadlock.RWMutex See PR #33069.) case may fail due to long
running time submitting tasks.
