<!-- If you need to report a security issue please visit https://github.com/apache/dubbo/security/policy -->
- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.
### Environment
* Dubbo version: 3.1.1
* Operating System version: linux
* Java version:1.8
### Steps to reproduce this issue
1. we use "offline" to shutdown dubbo app gracefully. when we offline more than two instances, it is possible for consumers to get the phenomenon.
reviewing the dubbo source code, we find that when offlining a instance it will remove services in "MetadataInfo" but
the field "revision of MetadataInfo" won't change in time. if a consumer requests metadatainfo from the offlining instance, it will response the metadatainfo without services.
Pls. provide [GitHub address] to reproduce this issue.

I'm afraid it is not repaired in 3.2.1.

It is not an exception. There's no stack information. But I use Arthas to debug the consumer, and then find a cue as the following image. We can see that the filed "services" is a empty array.

Can you provide abnormal stack information? I also use offline commands for offline traffic and have not encountered this issue before. Version 3.1.0
