Log:
  lualoader: Invalidate the screen from menu perspective upon mnu exit
  
  In the common case, this will effectively do nothing as the menu will get
  redrawn as we leave submenus regardless of whether the screen has been
  marked invalid or not
  
  However, upon escape to the loader prompt, one could do either of the
  following to re-enter the menu system:
  
  -- Method 1
  require('menu').run()
  
  -- Method 2
  require('menu').process(menu.default)
  
  With method 1, the menu will get redrawn anyways as we do this before
  autoboot checking upon entry. With method 2, however, the menu will not be
  redrawn without this invalidation.
  
  Both methods are acceptable for re-entering the menu system, although the
  latter method in the local module for processing new and interesting menus
  is more expected.
