hal: set initial value of stop_threshold for compress voip

Member stop_threshold of pcm_config for compress voip is not
initialized, then it will be set to default value equals to
buffer size during pcm_open. XRUN may happen and stop the
stream due to delayed writes to fill buffers. When stream is
restarted, path configuration could fail and cause RX mute.
Set the intial value to INT_MAX to avoid XRUN.
