hal: passthru: Fix to avoid mute in DDP passthru 

-Mute ovserved on HDMI sink while rendering
high bitrate DDP content
-Offload buffer size is just 2k,
increasing it to handle high bit rate content
-QAF: Session close is blocked if pcm stream open is failed
--This is fixed by cleaning up the pcm stream
