net/ipv6: fix metrics leak
Since commit d4ead6b3 ("net/ipv6: move metrics from dst to rt6_info"), ipv6 metrics are shared and refcounted. rt6_set_from() assigns the rt->from pointer and increases the refcount on from's metrics. This reference is never released. Introduce the fib6_metrics_release() helper and use it to release the metrics.
