[Docs] Add info about incompatible PF configuration in ML2/OVN gaps

* Floating IP Port Forwarding in provider networks and with distributed routing
Currently, when provider network types like ``vlan`` or ``flat`` are plugged
to a router as internal networks while the ``enable_distributed_floating_ip``
configuration option is enabled, Floating IP port forwardings
which are using such router will not work properly.
Due to an incompatible setting of the router to make traffic in the vlan/flat
networks to be distributed but port forwardings are always centralized in
ML2/OVN backend.
This is being reported in [13]_.
