ah ok, it's not the commit above then, it's this one is the issue

commit 81e025d7ed6a802845909df6fb90505508dc0fbf
Author: Xuan Ding <xuan.ding@intel.com>
Date:   Wed Apr 29 02:59:46 2020 +0000

    vhost: prevent zero-copy with incompatible client mode

    [ upstream commit 715070ea10e6da1169deef2a3ea77ae934b4c333 ]

    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.
--

It's unfortunate that it is both fixing a bug and removing functionality
at the same time :/

Yes, these patches are already in 19.11.3.
