Takashi Iwai 094435d41d ALSA: pcm: Avoid double hw_free calls at releasing a stream 
snd_pcm_release_substream() always calls hw_free op when the stream
was opened.  This is superfluous in most cases because it's been
already released via explicit hw_free ioctl.  Although this double
call is usually OK as this callback should be written to be called
multiple times, it's better to avoid superfluous calls.
