    wg: Improve wg_clone_destroy() and wg_down()
    
    - Move the cancellation of tasks from wg_clone_destroy() to wg_down(),
      which is actually more appropriate.
    - Just call wg_down() in wg_clone_destroy() to reduce duplicate code.
    - No need to call if_purgeaddrs_nolink(), as it will be called by
      if_detach().
    - Detach and free the interface before destroying the aip radix trees,
      in order to avoid possible panics.
