Function snd_pcm_ioplug_hw_ptr_update can be called from many threads, we
need to protect the hw_ptr. I came across this issue with GStreamer and
Jackd. Function will be called from the thread doing snd_pcm_write and
another would be to get the playback position for the track bar.
Change in itself is very minimum, but it took me a lot of time to debug.
