pcm: Fix memory leak at snd_pcm_new when THREAD_SAVE_API is defined

[GitHub pull_request - opened]

alsa-project/alsa-lib pull request #42 was opened from chunxuxiao:

The pthread_mutexattr_t object should be destroyed by calling
pthread_mutexattr_destroy(), otherwise it may cause a potential
memory leak due to the different implement of pthread_mutexattr_init()
