Only pass stack.Route's fields to LinkEndpoints

stack.Route is used to send network packets and resolve link addresses.
A LinkEndpoint does not need to do either of these and only needs the
route's fields at the time of the packet write request.

Since LinkEndpoints only need the route's fields when writing packets,
pass a stack.RouteInfo instead.
