Anything that has not been seen bofore arriving on the WEP is clearly from the host and so we should return any responses through the host as well. This also effectively disables conntrack bypass for traffic that is returning from a workload to a pod. This allow returning traffic to go through iptables rules that previously could have affected inbound traffic - similar rules like the ones inject by Istion in ambient mode. fixes projectcalico#9157
