The allocated memories by snd_pcm_new() are freed automatically.
The private_free callback is for extra memory that is allocated in the
outside.  But in this case, it's the chip object that will be freed
snd_korg1212_dev_free(), so snd_korg1212_free_pcm() doesn't do
anything.  (Actually it can be dropped.)
