Takashi Iwai 635c265f32 ALSA: ctxfi - Replace atc lock to mutex
The spinlock in atc can cause a sleep in lock:

Kernel failure message 1:
BUG: sleeping function called from invalid context at mm/slub.c:1599
in_atomic(): 0, irqs_disabled(): 1, pid: 2537, name: gstreamer-prope
Pid: 2537, comm: gstreamer-prope Tainted: P

  ...

Since the lock path is no critical path, it can be gracefully
replaced with a mutex.
