change the name to audio_wrapper_, and update the comment.

I would like to keep this notation to match the corresponding output code (see
ppapi/shared_impl/ppb_audio_shared.cc). They both map shared memory into an
audio bus and I have used it as reference here. Makes it easier to compare and
harmonize in the future. Hope that is OK.
