The error logs said the resource is already locked, this means, the ZNODE of this namespace bundle created by previous broker was not removed yet.
Normally, broker would firstly query the bundle owner before tried to acquire it.

```
public CompletableFuture> getOwnerAsync(NamespaceBundle suName) {
CompletableFuture ownedBundleFuture = ownedBundlesCache.getIfPresent(suName);
if (ownedBundleFuture != null) {
// Either we're the owners or we're trying to become the owner.
return ownedBundleFuture.thenApply(serviceUnit -> {
// We are the owner of the service unit
return Optional.of(serviceUnit.isActive() ? selfOwnerInfo : selfOwnerInfoDisabled);
});
}

// If we're not the owner, we need to check if anybody else is
String path = ServiceUnitUtils.path(suName);
return lockManager.readLock(path);
}
```

If the ZNODE created by previous broker was not removed yet. Why `lockManager.readLock(path)` returned none owner of this bundle.

#### Reproduce step.

It's hard to reproduce, since i just unloaded some bundle during the consumer and producer exists,.

Start with NamespaceService.java:577 and getOwnerAsync, then trace LockManagerImpl.acquireLock and ResourceLockImpl revalidation using the reported ZKMetadataStore stack. Determine why readLock reports no owner while acquisition reports LockBusyException; done means a reproducible explanation and a verified resolution.
