+Fix leak in PredictorSetupDecode by calling tif_cleanup on failure
+
+tif_data and tif_cleanup are both set on the TIFFInit methods, see for
+instance TIFFInitPixarLog. If PredictorSetupDecode fails, whatever was
+filled on tif_data should be cleaned up. The previous leak fix from
+PixarLogSetupDecode is no longer necessary.
