runtime: drop redundant argument to getArgInfo
runtime: drop redundant argument to getArgInfo

The f funcInfo argument is always the same as frame.fn, so we don't
need to pass it. I suspect that was there to make the signatures of
getArgInfoFast and getArgInfo more similar, but it's not necessary.

For #54466.
