ALSA: pcm - Fix unbalanced pm_qos_request
The pm_qos_request isn't freed properly when OSS PCM emulation is used because it skips snd_pcm_hw_free() call but directly releases the stream. This resulted in Oops later. Tested-by: Simon Kirby <sim@hostway.ca> Signed-off-by: Takashi Iwai <tiwai@suse.de>
