It appears that some older drivers do not support CreateSwapChainForHwnd, resulting in DXGI_ERROR_INVALID_CALL. For these cases, fall back to the base CreateSwapChain() from DXGI 1.0. In theory this should also let us run on Win7 without the platform update, but in reality we require the newer shader compiler so this probably won't work regardless. Also any hardware of this vintage is unlikely to run Dolphin well.
