Modified submix HAL to drop data to the output stream if the pipe could block.
Since it's possible to open an output stream on the submix HAL before the input
stream is open, writes to the output stream that fill the shared pipe result in
indefinitely blocking the thread writing to the stream. This change modifies
the behavior of writes to a submix output stream such that if a write would
result in blocking the thread and an input isn't open, the pipe is flushed
of the appropriate amount of data such that the write will not block.
