Description of problem:

Deploy dualstack OCP cluster with baremetal worker nodes and then enable ovs harward offload by creating sriovnetworkpoolconfig with yaml below, ovnkube pods of the baremetal workers crashed. 
Check 'ovs-vsctl show' in the worker nodes, physical inteface is no longer under br-ex.

# cat sriov_pool.yaml

kind: SriovNetworkPoolConfig

How reproducible:

Steps to Reproduce:

1. Deploy dualstack cluster and add baremetal hosts as worker nodes.
2. install sriov network operator
3. Enable ovs hardware offload by creating yaml below
# cat sriov_pool.yaml  apiVersion: sriovnetwork.openshift.io/v1 kind: SriovNetworkPoolConfig metadata:   name: sriovnetworkpoolconfig-offload   namespace: openshift-sriov-network-operator spec:   ovsHardwareOffloadConfig:     name: sriov
4. check ovnkube pods 
5. check 'ovs-vsctl show' in worker node.

Actual results:

ovnkube pods crashed

Expected results:

ovnkube pods should not crash
