ALSA: pcm: Unify snd_pcm_group initialization
There are multiple open codes that initialize the same object. Create a common helper function instead. Also, use kzalloc() to be safer at creating a group object, and move the initialization out of the critical section. Signed-off-by: Takashi Iwai <tiwai@suse.de>
