Public bug reported:

Reported at https://bugzilla.redhat.com/show_bug.cgi?id=2219405

Enabling the mcast_flood_reports for ports from other types other than
"localnet" was a workaround for a problem in core OVN that is now fixed
(see [0]).

Leaving mcast_flood_reports enabled is now overflowing the number of
actions in the table 38 of OVN. So we should disable that in ML2/OVN.
