soundstream: fix i2s_wait_for_rx_watermark

Having multiple waiters on the RxWatermarkInterrupt futex only works
if the waker explicitly asks for multiple threads to be woken (the
expectation is MultiWaiter will be used in this case). This broke with
the tickless scheduler. Fix is to introduce a separate futex to wait
for rx_watermark_seen.
