Description

The fix for https://issues.apache.org/jira/browse/KAFKA-14039 adjusted the invocation of the alter configs policy check in KRaft to match the behavior in ZooKeeper, which is to only provide the configs that were explicitly sent in the request. While the code was correct for the incremental alter configs case, the code actually included the implicit deletions for the legacy/non-incremental alter configs case, and those implicit deletions are not included in the ZooKeeper-based invocation. The implicit deletions should not be passed in the legacy case.
