Review comment:
yes, we trigger the callback but we missed to reduce to refCnt of `payload`
in producer so, when [callback receives
callback](https://github.com/apache/pulsar/blob/master/pulsar-client/src/main/java/org/apache/pulsar/client/impl/ProducerImpl.java#L257),
it tries to release payload with refCnt=2 so, producer doesn't release the
actual payload.
