Tong Zhang 2108cc7290 stge: fix null pointer dereference ... stge_attach() could fail at line 464, sc->sc_spec remains NULL when calling stge_detach(), thus bus_release_resources() at line 704 will trigger null pointer dereference. We need to check the nulliness before calling bus_release_resources().
