Sarama retry since v8.5.7 may make the sink stuck forever on transient error

### What did you do?

* Create a Kafka changefeed
* Keep writing data until the Kafka reported some transient errors ("broken pipe" etc) (?)


### What did you expect to see?

* Automatic retry allowed the message to be written.

### What did you see instead?

* The sink is stuck not confirming success or failure, and thus CheckpointTS is stuck.

### Versions of the cluster

v8.5.7
