lua: workaround false positive dereference of null pointer
scan-build from clang-9 has reported following: ubus.c:837:16: warning: Access to field 'rnotify' results in a dereference of a null pointer (loaded from variable 'sub') sub->rnotify = luaL_ref(L, -2); Which is false positive as the lua_error() does a long jump and therefore never returns and this long jump probably confuses the static analyzer. So this patch workarounds this false positive by helping static analyzer by using common Lua idiom which is to return lua_error()'s return value.
