[GitHub] trafficserver issue #1401: Segfault in write_to_net_io with 7.1.x

    epoll_wait triggered EVENTIO_ERROR after accept(do_blocking_accept) will cause  coredump, because we do not call any do_io_xx. In 6.x.x we do not handle EVENTIO_ERROR event\uff0cit may cause vc leaking, but avoid coredump.
    `  while ((vc = write_ready_list.dequeue())) {
        set_cont_flags(vc->control_flags);
        if (vc->closed)
          close_UnixNetVConnection(vc, trigger_event->ethread);
        else if ((vc->write.enabled || vc->write.error) && vc->write.triggered)
          write_to_net(this, vc, trigger_event->ethread);
        else if (!vc->write.enabled) {
          write_ready_list.remove(vc);
    #if defined(solaris)
          if (vc->write.triggered && vc->read.enabled) {
            vc->ep.modify(-EVENTIO_WRITE);
            vc->ep.refresh(EVENTIO_READ);
            vc->readReschedule(this);
          }
    #endif
        }`
