scripts/kernel-doc: warn on excess enum value descriptions
The existing message "Excess struct/union/enum/typedef member [...]" made it sound like this would already be done, but the code is never invoked for enums or typedefs (and really can't be). Add some code to the enum dumper to handle this there instead. While at it, also make the above message more accurate by simply dumping the type that was passed in, and pass the struct/union differentiation in.
