KAFKA-5438: Fix UnsupportedOperationException in writeTxnMarkersRequest
Before this patch, the `partitionErrors` was an immutable map. As a result
if a single producer had a marker for multiple partitions, and if there were
multiple response callbacks for a single append, we would get an
`UnsupportedOperationException` in the `writeTxnMarker` handler.
