d3d9/tests: Restore display modes at the end of test_wndproc().

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.
