net: sched: uapi: add more sanely named duplicate defines

The TCA_FLOWER_KEY_CFM enum has a UNSPEC and MAX with _OPT
in the name, but the real attributes don't. Add a MAX that
more reasonably matches the attrs.

The PAD in TCA_TAPRIO is the only attr which doesn't have
_ATTR in it, perhaps signifying that it's not a real attr?
If so interesting idea in abstract but it makes codegen painful.
