vcl: hold errno when calling LDBG
Type: fix Call trace of LDBG: LDBG->clib_warning->_clib_error->dispatch_message->os_puts->writev However, writev will hijacked by LDP, and then execute following code: if ((errno = -ldp_init ())) return -1; Now, errno will be set. Because we always call LDBG just before return from ldp_accept4, listen, and etc. So errno will be overwritted after LDBG called.
