  Log Message:
  -----------
  loadLayerCompositer(): fix memleak in error code paths

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=57261

The manual cleanup that was done was incomplete (it should have called
freeCompositingFilter()), and it is actually useless as the caller
loadLayer() takes care of cleaning.
