Nest: Fix route update after preference change

The route preference was ignored in route comparison, therefore if
a protocol changed it and then reloaded routes, they were ignored
and routes with the old prefernce were kept.

The bug was introduced 5 years ago, when preference was moved from
struct rte to struct rta.
