Xuan Ding 715070ea10 vhost: prevent zero-copy with incompatible client mode 
In server mode, virtio-user inits under the assumption that vhost-user
supports a list of features. However, this could be problematic when
in_order feature is negotiated but not supported by vhost-user when
enables dequeue_zero_copy later.

Add handling when vhost-user enables dequeue_zero_copy as client.

Fixes: 64ab701c3d ("vhost: add vhost-user client mode")
