cni: Assign the netpair for virtual endpoints after scan

In addition to the DNS, we need to copy the netpair struct as well
from the endpoint structures we created prior to the network creation
to the endpoints created after scanning the network.

This is needed for creating the tap and bridge interfaces for virtual
endpoints.
