Context: https://codereview.webrtc.org/2739073003/diff/280003/webrtc/audio/utility/audio_frame_operations.h To satisfy cpplint, the signature of the Scale* methods needed to be changed from a reference to a pointer. However, not to break internal users, the old signature was kept temporarily. Now it can be removed because it's not used anymore.
