PR body: """ autofs_map_result_timeout() is called as a timed event to free the autofs map data is the cache lifetime is exceeded. If the data is freed earlier the timed event should be removed as well to avoid a double free issue. Since talloc is used here the most easy way to achieve this is to allocate the timed event on the map object itself.
