Description of problem:
IPFailover preemption does not work on OCP4.9.

When the customer sets OPENSHIFT_HA_PREEMPTION=nopreempt and checks the VIP after stopping/starting the node, the VIP that was moved to another node returns to the original node after 1 minute.

It appears that the environment variable is not working because the VIP returns after 1 minute even if the customer sets PREEMPT_NODELAY 300 to test it.

Version-Release number of selected component (if applicable):
OpenShift Container Platform 4.9

How reproducible:
Steps to Reproduce:
1. set OPENSHIFT_HA_PREEMPTION=nopreempt
2. stop and start the master node

Actual results:
When nopreempt is set, the VIP continues to move on the other node.

Expected results:
The VIP returns the original node.
