Backward compatible for pcm_write() pcm_read()
Current return value of pcm_write()/pcm_read() comes from pcm_writei()/pcm_readi() which is the actual frames written/read. But the old pcm_write() /pcm_read() just returns 0 on success and a nagative value on error. This change will keep the pcm_write()/pcm_read() as the old behavior which has been already used by many applications, and is also matching the comment above each function.
