wined3d: Get rid of the "swapchain" parameter to surface_get_gl_buffer().

Browse Source 
Casting the container to "IWineD3DSwapChainImpl *" is always safe when
SFLAG_SWAPCHAIN is set on the surface. Most callers don't have a real
need for the swapchain, and end up calling GetContainer() just to pass
it to surface_get_gl_buffer().
