zebra: when parsing local entry against dad, retrieve config

Browse Source 
when duplicate address detection is observed, some incrementation,
some timing mechanisms need to be done. For that the main evpn
configuration is retrieved. Until now, the VRF that was storing the dad
config parameters was the same VRF that hosted the VXLAN interface. With
netns backend, this is not true, as the VXLAN interface is in the
same VRF as the bridge interface. The modification takes same definition
as in BGP, that is to say that there is a single bgp evpn instance, and
this is that instance that will give the correct config settings.
