A previous PR (#71573) intended to clear conntrack entry on endpoint
changes when using nodeport by introducing a dedicated function to
remove the stale conntrack entry on the node port and allow traffic to
resume. By doing so, it has introduced a nodeport specific bug where the
conntrack entries related to the ClusterIP does not get clean if
endpoint is changed (issue #96174). We fix by doing ClusterIP cleanup in
all cases.
