clutter/actor: Initialize out variable

Browse Source 
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.
