    plug-ins: return proper non-success status in file-pdf.
    
    When not creating an image, we were always returning with status
    GIMP_PDB_EXECUTION_ERROR even though it might have been GIMP_PDB_CANCEL
    (which is not handled as an error, this is user choice, hence no dialog
    pops up).
