When a port is down, the FIP associated to it get centralized
(external_mac removed on NAT table entry) despite DVR being enabled.
This also happen when deleting a VM with a FIP associated, where during
some period of time, the FIP gets centralized -- time between removing
the external_mac from NAT table entry, and the deletion of the NAT table
entry.
