Enable neutron-dynamic-routing service plugin

Upstream Neutron has declared that the neutron-dynamic-routing service
plugin is now supported when OVN L3 service plugin and mechanism driver
are in use.

https://review.opendev.org/c/openstack/neutron/+/864051
4d1a7bd0bc

This change removes the NDR plugin from the filter so that the plugin
is enabled.
