[UTC][audio-io][Non-ACR] change waiting logic of stream callback due to platform...

As platform code updated due to request of removing initial latency in audio-io,
stream callback invoked earlier than waiting lock logic, therefore deadlock happens.
code changed to handle even callback invoked earlier than expected.
