[Bug] about metrics bug

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.

### Version

2.8.4
java8
linux

### Minimal reproduce step

1. Create springboot program integrated with pulsar2.8.4
2. Produce and consume at the same time
3. Modify the code and restart repeatedly during the consumption process
4. Check the status of the topic on the pulsar manage page and check the interface response data. It is found that msgInCounter in the response data is less than msgOutCounter in the subscriber.

### What did you expect to see?

msgInCounter is equal to or greater than msgOutCounter

### What did you see instead?

Check the status of the topic on the pulsar manage page and check the interface response data. It is found that msgInCounter in the response data is less than msgOutCounter in the subscriber.

### Anything else?

_No response_

### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

No source file or test is named. Start by reproducing the issue with Pulsar 2.8.4, Java 8, Linux, and a Spring Boot producer/consumer while repeatedly restarting during consumption. Compare the topic management page and interface response values for msgInCounter and msgOutCounter; done means the counters satisfy the expected relationship under this scenario.
