networkd: avoid NULL pointer dereference in route_add
If no result parameter is provided, do not attempt to write the
found/newly-created route to it. This is presently not an issue as all
callers currently provide a non-NULL result parameter, however we should
do this for symmetry with address_add and future code robustness.
