ALSA: hda - create hda_codec.control_mutex for kcontrol->private_value
Fix the following lockdep warning by not reusing the hda_codec.spdif_mutex.
ALSA sound/pci/hda/hda_codec.c:882: hda_codec_cleanup_stream: NID=0x2
=======================================================
[ INFO: possible circular locking dependency detected ]
2.6.28-next-20090102 #33
-------------------------------------------------------
mplayer/3151 is trying to acquire lock:
(&pcm->open_mutex){--..}, at: [<ffffffffa004ced3>] snd_pcm_release+0x43/0xd0 [snd_pcm]
but task is already holding lock:
(&mm->mmap_sem){----}, at: [<ffffffff810c0252>] sys_munmap+0x42/0x80
which lock already depends on the new lock.
