vxlan: Protect against tunnel config where source is not local
Type: fix If a tunnel's source is not local then post encap VPP will attempt to receive (via ip4-local) that packet, things go wrong from there. The fix is when stacking the encap forwarding don't accept a receive DPO. This approach is taken, rather than rejecting bad tunnels, because the 'local-ness' of the tunnel's source can change and we can't reject tunnels that were once correctly configured but are no longer. the user will quickly discover their mistake as traffic won't pass.
