device: avoid accidentally changing route-metric during config-reloadth/device-reapply-metric

It's not properly implemented, to change the route-metric while
being active. That would require pecular re-initializations.

Avoid that a configuration reload, can change the used route-metric
unexpectedly.

It doesn't cover all potential changes, because
nm_manager_device_route_metric_reserve() might still return a different
value. That is however rather unlikely, because neither the ifindex nor
the device-type is expected to change.
