clientv3: only receive from closing streams in Watcher close
...
Was overcounting the number of expected closing messages; the resuming
list may have nil entries. Also the full client wasn't closing the watcher
client, only canceling its context, so client closes weren't joining with
the watcher shutdown.
Fixes #6605

clientv3: fix race on watch initial revision
...
The initial revision was being updated in the substream goroutine defer;
this was racing with the resume path fetching the initial revision when
the substream closes during resume. Instead, update the initial revision
whenever the substream processes a new watch response. Since the substream
cannot receive a watch response while it is resuming, the write to the
initial revision is ordered to always happen after the resume read.
