compositor: Fix warning with -Wmaybe-uninitialized

Assert that the region is created, thus we passed a valid enum value
to the get_scaled_region() function. Fixes:

  ../../../../Source/gnome/mutter/src/compositor/meta-surface-actor.c: In function ‘get_scaled_region’:
  ../../../../Source/gnome/mutter/src/compositor/meta-surface-actor.c:113:10: warning: ‘scaled_region’ may be used uninitialized in this function [-Wmaybe-uninitialized]
    113 |   return scaled_region;
        |          ^~~~~~~~~~~~~
