- Fixed incorrect behavior of preemptor pod when preemption of the victim takes long to complete. The preemptor pod should not be circling in scheduling cycles until preemption is finished.

* Fix a race condition in the scheduler preemption logic that could cause nominatedNodeName of a pod not to be considered in one or more scheduling cycles. ([#72259](https://github.com/kubernetes/kubernetes/pull/72259), [@bsalamat](https://github.com/bsalamat))
