Use the mangle checksum fill rule regardless to the multi_host

The checksum-fill is required even when you are running devstack,
in a nested kvm guest.
Always using the checksum-fill on all dhcp responses is safe, and does
not have significant impact.

The situation is similar when the checksum-fill first introduced to
nova.
