[8u60] Request for review: RT-37900: MP3 player fails to exit

[Kirill Kirichenko]

Hi Alexander.
Could you please review this fix for directshowwrapper.
When working with fuzzed mp3 files decoder->pSrc->DeliverSample fails 
but no error is generated and the whole pipeline just silently swithces 
to prerolling.
