Review Comment:
I was looking at the AlterPartition API as a reference. There, when we have
a top level error, we don't set the partitions in the response at all. We
basically save space. See
[here](https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/requests/AlterPartitionRequest.java#L46).
