compositor: fix possible crash closing/destroying window
Partially restore call to destroy_win in compositor when calling meta_window_free. This is needed to ensure that we never call meta_window_get_frame_bounds while windows is destroying. https://bugzilla.gnome.org/show_bug.cgi?id=751833 upstream commit: https://gitlab.gnome.org/GNOME/metacity/commit/a9f28dbc
