On update of any interface (set up/down) a routing preference is updated calling esp_netif_update_default_netif() that is called from lwip context. But if the related netif was ppp type, the set_default api used user-mode, thus causing a dead lock. Closes https://github.com/espressif/esp-idf/issues/4746
