plug-ins: Fix crash when loading CMYK JPEG 2000 images

Browse source 
When converting a CMYK JPEG 2000 image to RGB, we freed
the Key array. Since it is still in use, this caused the
plug-in to crash. This patch replaces this with lowering
the component content and letting the OpenJPEG clean up
process handle this work instead.
