Takashi Iwai 1cb217ead9 ALSA: pcm: Use recursive mutex 
The recent thread-safety pthread implementation caused deadlocks in
some situations, e.g. when an external plugin calls snd_pcm_state() in
its callback.  One can avoid the deadlock by carefully using the
unlocked version, but it's often error-prone, and it might be still
problem with the old binaries.

In this patch, we initialize the pthread mutex as recursive for fixing
such a problem.
