Jira: https://issues.apache.org/jira/browse/KAFKA-20777
When transactional state stores are enabled (enable.transactional.statestores=true), an open StagedMergeIterator that is used after the store is closed throws java.lang.IllegalStateException("Iterator has already been closed.") from StagedMergeIterator.hasNext(), for consistency with the other managed store iterators (e.g. RocksDbIterator), it should throw InvalidStateStoreException.
