Description: https://github.com/apache/kafka/pull/10494 introduced a bug in
the KRaft controller where the controller will loop forever in

requested partitions in a CREATE_TOPICS request is greater than 1. (was:
https://github.com/apache/kafka/pull/10494 introduced a bug in the KRaft
controller where the controller will loop forever in `StripedReplicaPlacer`
trying to identify the racks on which to place partition replicas if the number
of requested replicas (i.e. replication factor) in a CREATE_TOPICS request
exceeds the number of effective racks ("effective" meaning a single rack if
none are specified).)
