KAFKA-13572 Negative preferred replica imbalance metric

Hi, Kafka.

We found that the race in topic-deletion procedure could cause the
preferred replica imbalance metric to be negative.
The phenomenon can easily happen when many topics are deleted at once, and
since we use the metric for monitoring, we have to restart the controller
to fix the metric every time it happens.

I submitted a patch to fix it: https://github.com/apache/kafka/pull/12405
It'd be appreciated if anyone could review the PR.


Thanks,
