Error logs are continuously printed when disconnected from Kafka

```python
consumer_ = aiokafka.AIOKafkaConsumer(
*topics,
bootstrap_servers=f"192.168.1.100:9092",
)
await consumer_.start()
try:
async for msg in consumer_:
print(msg)
finally:
await consumer_.stop()
```
`aiokafka` outputs a lot of error logs when I disconnect from 192.168.1.100 :

```
ERROR | aiokafka.consumer.fetcher:_proc_fetch_request:658 - Failed fetch messages from 3: KafkaConnectionError: Connection at 10.64.73.35:9094 closed
ERROR | aiokafka.client:_get_conn:460 - Unable connect to node with id 3: [WinError 1232]
