[PATCH 2/4] dsound: Reject NaN values in IDirectSound3DListener::SetOrientation().

[Aida Jonikienė]

From: Aida Jonikienė

GTA San Andreas calls this function with NaN positions under certain
circumstances which eventually results in dwTotalAmpFactor value
being really high (and causing extremely loud audio output).
