Pods behind MetalLB load balancer ain't reachable when service is configured with externalTrafficPolicy: Local

Version-Release number of selected component (if applicable):
4.17.0-rc.5

How reproducible:
so far 100%

Steps to Reproduce:

1. Create a deployment

2. Create a service of LoadBalancer type with externalTrafficPolicy set to Local

3. Create EgressService

4. Access backend pods via LoadBalancer's IP address

Actual results:
Fail to reach backend pods

Expected results:
Backend pods are reachable via LoadBalancer's IP address

Additional info:

Dualstack baremetal cluster with bonds, OVN configured with Local GateWay and routingViaHost enabled.

NNCPs configure VRFs on the nodes

Same config works with externalTrafficPolicy set to Cluster.
Also externalTrafficPolicy: Local worked on 4.16.13
