esp32/network_ppp: Block after deleting task.

When calling ppp.active(False) we could get a crash due to immediately returning after asking FreeRTOS to delete the current task. This commit adds a simple blocking loop, the same as used in all other places where we call vTaskDelete(NULL). Signed-off-by: Daniël van de Giessen <[email protected]>
