vo_direct3d: create multithreaded IDirect3DDevice9
A user complains that it leads to the dxva driver failing, leading to messages like this: [ffmpeg/video] h264: Failed to execute: 0x8007000e [ffmpeg/video] h264: hardware accelerator failed to decode picture Reportedly, this happens only with vo_direct3d, not with vo_opengl. The only difference is that vo_direct3d attempts to share the D3D device with the decoder. Possibly the error is that the device in the VO is not created with D3DCREATE_MULTITHREADED. Change this. Probably fixes #2178.
