[PATCH v2 2/7] d3d9/tests: Restore display modes at the end of test_wndproc().

[Zhiyi Zhang]

test_wndproc() makes a series of ChangeDisplaySettings() calls that could make the current display
mode no longer match the registry display mode. Restore display modes at the end of test_wndproc()
so that other tests are not affected.
