URL: https://github.com/apache/kafka/pull/12405
* Currently, `preferredReplicaImbalanceCount` calculation has a race that
becomes negative when topic deletion is initiated simultaneously.
* Please refer [KAFKA-13572's
comment](https://issues.apache.org/jira/browse/KAFKA-13572?focusedCommentId=17566872&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17566872)
for the details
* This PR addresses the problem by fixing
`cleanPreferredReplicaImbalanceMetric` to be called only once per
topic-deletion procedure
