**Expected behavior**
Able to restart and run broker without any error.
Claimed to be fixed by #10968, but I still face the same issue.

**Additional context**
Pulsar version: 2.8.1
Pulsar mode: cluster, 3 nodes
KoP: enabled (#10950)

Start with FunctionMetaDataManager.initialize and the ConsumerImpl.hasMessageAvailable and ReaderImpl.hasMessageAvailable stack-trace entries. Reproduce the broker restart failure in the reported 2.8.1 three-node cluster with KoP enabled, then compare the behavior with issues #11774, #10967, and fix #10968. Done means the broker restarts without the BrokerMetadataException.
