In the functions, Factory::CreateBGRA8DataSourceSurfaceForD3D11Texture() is called. It caused to block Renderer thread during mozilla::gfx::Factory::ReadbackTexture().

It seemed that we do not have a good way to prevent readback in D3D11TextureIMFSampleImage::GetAsSourceSurface(). Then it seems better to reduce the GetAsSourceSurface() call for now like Bug 1889275.
