Bug 1885153

Description of problem:
Cirros VM on RHV with 2 nics of ovirtmgmt/ovirtmgmt.
These 2 negative test cases end up with this error:
"cirros-import could not be imported.
DataVolumeCreationFailed: Error while importing disk image: . VirtualMachine.kubevirt.io "" not found "

Case 1: Map networks to: 
          1. Pod network
          2. ovn-kubernetes1 
Resource mapping -
spec:
  ovirt:
    networkMappings:
    - source:
        name: ovirtmgmt/ovirtmgmt
      target:
        name: pod
      type: pod
    - source:
        name: ovirtmgmt/ovirtmgmt
      target:
        name: ovn-kubernetes1
      type: multus

Case 2: Map 2 networks to pod. Resource mapping -
spec:
  ovirt:
    networkMappings:
    - source:
        name: ovirtmgmt/ovirtmgmt
      target:
        name: pod
      type: pod
    - source:
        name: ovirtmgmt/ovirtmgmt
      target:
        name: pod
      type: pod
Version-Release number of selected component (if applicable):
CNV-2.5

Expected results:
There should be an error indicating that there is a mistake in the network mapping, 
Case 1. should fail on not be possible to map the same vnic profile to 2 different networks.
Case 2 should fail on more than one network interface mapped to a pod network is not allowed (either because that was specified explicitly or the nics share the same vnic profile).

Additional info:
How the 2nd network was added to CNV:
$ oc apply -f second_network.yaml

second_network.yaml:
apiVersion: "k8s.cni.cncf.io/v1"
kind: NetworkAttachmentDefinition
metadata:
  name: ovn-kubernetes1
spec:
  config: '{
      "cniVersion": "0.3.1",
      "type": "cnv-bridge",
      "bridge": "br1"
    }'
