In stable/liberty, update port's binding:host_id doesn't report any error, but this field is none when you do port-show.
e.g.
stack@htb-1n-eng-dhcp8:~/devstack$ neutron port-update test-port --binding:host_id=htb-1n-eng-dhcp8
Updated port: test-port
stack@htb-1n-eng-dhcp8:~/devstack$ neutron port-show test-port
