Just a minor code optimization to reduce the source code size
slightly.  No functional changes.

Won't be better to define those two above functions as inline now?

That's possible, but then we'd need to export snd_proc_root.  Also
snd_info_create_entry() is a local function right now, so we'll need
to export this one, too.  Overall, there won't be any big gain, I
guess.
