To fix the issue that watchdog reset hang issue. At previous change, we assume the reset comes from guest. But watchdog reset or dm killed by signal is different. It's possible the vm_loop stick on ioreq attaching. The new fixing has two parts: - fixing from kernel side to remove the race issue in ioreq attach, req_complete_notify and client destory. - Move the client destroy before waiting of vm_loop exit.
