Producer silently swallows produce error if it does not have Write permissions

Description
===========
We have a producer that produces to a topic and does not have Write permissions on it. If I would produce to it, I would expect the produce call to throw an exception. Instead, librdkafka only logs `PARTCNT|rdkafka#producer-3| [thrd:ssl://localhost:9090/]: Topic test-topic partition count changed from 3 to 0`.

I do produce an `on_delivery` callback and also call `producer.flush()` and `producer.poll()` after the produce.

I found some older related issues https://github.com/confluentinc/confluent-kafka-python/issues/738 and https://github.com/confluentinc/confluent-kafka-python/issues/704 which are already closed with `v1.6.0, will provide improved authentication error reporting`. There is also this recently opened issue https://github.com/confluentinc/confluent-kafka-python/issues/1787 for a similar problem on the consumer.

How to reproduce
================
Initialize a producer without Write permissions and then run
```
def delivery_report(err: KafkaError, msg: Message) -> None:
raise RuntimeError(err)

producer.produce("topic", "value", on_delivery=delivery_report)
producer.flush(timeout=1.0)
producer.poll(timeout=0)
```

You will observe the log message, but no error will be raised.
