audio: remove W/A codes for winwaveaudio

When sound is played without connecting of speaker on Windows,
because winwaveaudio made process lock-up, the W/A were applied.
However, qemu of tizen_3.0 does not support winwaveaudio,
but, dsoundaudio for Windows host.
And, as audio codes of qemu are updated, the W/A is no more valid code.
Therefore, the W/A codes are removed.
