[PATCH 1/2] interface-ip: use metric when looking for a route

[luizluca at gmail.com]

From: Luiz Angelo Daros de Luca <luizluca at gmail.com>

When there were multiple routes with the same target but different
metrics, __find_ip_route_target was returning the first one,
independently of the metric.
