Review Comment:
The source of `fetchPartitionStatus` comes from `fetchData()`.
https://github.com/apache/kafka/blob/53e117253d21b2cd00e69d6ab91dae0ee84432f2/clients/src/main/java/org/apache/kafka/common/requests/FetchRequest.java#L395-L420
Its type is `LinkedHashMap<TopicIdPartition, PartitionData>`, so there will
be no duplicate TPs.
