scripts: kernel_doc: better handle show warnings logic
The logic with inhibits warnings for definitions that is not output is incomplete: it doesn't cover the cases where OUTPUT_INTERNAL and OUTPUT_EXPORTED are used. As the most common case is OUTPUT_ALL, place it first, in order to optimize a litte bit the check logic.
