Add a dx version check before calling SetDisplayMode in
D3DSwapChainImpl_Destroy

D3DSwapChainImpl_Destroy() function in dlls/wined3d/swapchain.c shouldn't call
SetDisplayMode() when D3D7 is used. This problem cause some 2D graphics
corruptions and switch to wrong screen resolution in Speed Busters game.
The patch in attachment add just a dx version check before calling
SetDisplayMode() to prevent a redundant call with one done by ddraw module.
