endpoint: Overwrite endpoint datapath config. on restore

On agent restarts, we serialize the endpoints to their header file to be
able to restore them afterward. That means we also restore their
datapath configuration regardless of any change in the agent's settings
(e.g., status of per-endpoint routes).

We therefore ignores changes to the per-endpoint routes setting
(enable-endpoint-routes).
