Merge pull request #44152 from NickrenREN/scheduler-bind

Browse Source 
Automatic merge from submit-queue (batch tested with PRs 43900, 44152, 44324)

Fix: check "ok" first to avoid panic

Check "ok" and then check if "currState.pod.Spec.NodeName != pod.Spec.NodeName", here if currState is nil, it will panic.

**Release note**:
```release-note
NONE
