[c-nsp] EIGRP, variance and offset-list out

[Andriy Bilous]

Notice that Advertised Distance (768) over Tunnel2 is now > Feasible
Distance (512) of the best route and as such this route can't be a
feasible successor, can't be considered as an alternative path and
therefore can't be installed in routing table. So, as long as
offset-list adds <=255, advertised distance is < FD=512 and both
routes are installed.
