[fix][broker] Producer still publishes messages to Broker after Topic was unloaded

[zhouyifan279]

Fixes apache#24792

Motivation

After unloading a bundle with many non-persistent topics from Broker, we found some producers in ProducerAccessMode.Shared mode were still publishing messages to the broker. Even thought the topic was not loaded by the broker any more.
