fix: query node may stuck at stopping progress

[weiliu1031]

issue: #33103 when try to do stopping balance for stopping query node, balancer will try to get node list from replica.GetNodes, then check whether node is stopping, if so, stopping balance will be triggered for this replica.

after the replica refactor, replica.GetNodes only return rwNodes, and the stopping node maintains in roNodes, so balancer couldn't find replica which contains stopping node, and stopping balance for replica won't be triggered, then query node will stuck forever due to segment/channel doesn't move out.
