1. Fix deregister dispatcher concurrency. (Keep sure the same logic as 2.5 branch) 2. Fix seek if includeCurrentMsg. (This is only needed by CDC, so there's no need to pick to 2.5 branch) issue: issue: https://github.com/milvus-io/milvus/issues/39862 pr: https://github.com/milvus-io/milvus/pull/39863 --------- Signed-off-by: bigsheeper <yihao.dai@zilliz.com>
