vhost_dev_cleanup(), called from vu_gpio_disconnect(), clears vhost_dev
so vhost-user-gpio must set the members of vhost_dev each time
connecting.
do_vhost_user_cleanup() should also acquire the pointer to vqs directly
from VHostUserGPIO instead of referring to vhost_dev as it can be called
after vhost_dev_cleanup().
