zebra: remove refcnt from the route_entry structure

This reference counter was introduced in 2001, apparently to solve a
problem with connected routes being added/removed multiple times. The RIB
code changed a lot since then, and giving the current callers of rib_add()
and rib_delete() it's safe to assume that we don't need this anymore.
