Add vhost-user protocol feature VHOST_USER_PROTOCOL_F_GET_VRING_BASE_INFLIGHT Now on GET_VRING_BASE this feature can control whether to wait for in-flight requests to complete or not. Also we have to validate that this feature will be enabled only when qemu and back-end supports in-flight buffer and in-flight migration It will be helpfull in future for in-flight requests migration in vhost-user devices.
