Ensure proxy arp and ndp is configure for flat provider networks

Browse Source 
If there are flat and vlan provider networks configured on the
same ovs provider bridge, the arp/ndp proxy were not being
configured for the bridge, therefore breaking the connectivity
to the VMs on the flat network. This patch ensures it is always
configured
