fix inconsistency in windows kernel proxy when updating hns policy

[delulu]

What this PR does / why we need it:

This PR removes the "svcInfo.policyApplied" check in cleaning up all the related HNS policies when a k8s service is removed.

Otherwise, kube proxy will go to an inconsistent state ( legacy HNS policy wont get removed in service cleanup, and new HNS policy creation will fail with error msg "The specified port already exists." ) :

1. when a k8s service is removed before all the HNS policies for this service are applied.

2. some HNS failure occurs during applying the HNS policies for this service.

Release note:

fix inconsistency in windows kernel proxy when updating HNS policy.

@feiskyer, thx for your tips. I already signed the CLA, how to ask the system to recheck my authorization?

Can you please add comment in this function that svcInfo.policyApplied check is not needed as we are trying to remove all policies?

@kubernetes/sig-contributor-experience-bugs Why does this want my approval? Why is it not enough to get someone in the OWNERS of the file in question?
