ao_sndio: open device in blocking mode, don't inflate buffer artificially 

The code actually uses blocking mode, so opening sound device in non-blocking
mode results in choppy sound.  Also, inflating the buffer isn't necessary in
blocking mode, so the function may simply return without doing anything.
