    clutter/actor: Initialize out variable
    
    Fixes a compiler warning with -Wmaybe-uninitialized enabled:
    
      ../../../../Source/gnome/mutter/clutter/clutter/clutter-actor.c: In function ‘clutter_actor_paint’:
      ../../../../Source/gnome/mutter/clutter/clutter/clutter-actor.c:3808:50: warning: ‘result’ may be used 
uninitialized in this function [-Wmaybe-uninitialized]
       3808 |       else if (result == CLUTTER_CULL_RESULT_OUT && success)
            |                ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~
    
    Which might presumably happen in the unlikely case that there's no clip
    frusta.
