[PATCH] perf/x86/intel/pt: Cleanup kernel-doc comments

[Lucy Mielke]

Some parameters or return codes were either wrong or missing, so I
cleaned it up to the best of my knowledge.

If anything I did was wrong, please let me know!

Your updates look correct to me too, thanks!

Applied to tip:perf/core, for a v6.7 merge. I changed the title, because 
these are not 'cleanups', but kernel-doc fixes for documentation annotation 
bugs that generate incorrect/misleading documentation.

Thanks,
