Currently there is no need to hook DefDlgProc(). Tests show that dialog theming shouldn't be implemented in DefDlgProc().
Also fix a double free bug because WM_DESTROY in UXTHEME_DefDlgProc() calls CloseThemeData() even when the theme handle is not opened when handling WM_CREATE in UXTHEME_DefDlgProc(). The bug can be demonstrated by running comctl32/tests/propsheet.c tests with Light theme.
