vhost-user-gpio: Configure vhost_dev when connecting
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().
