l2-population : update_port --admin_state_up False doesn't remove flooding entries

[Mathieu Rohon]

I run in multi node setup with ML2, L2-population and Linuxbridge MD, and vxlan TypeDriver.

I create 2 VMs on different nodes. When a port gets down on a node with :
neutron update_port <port_uuid> --admin_state_up False

Unicast fdb entries are correctly removed but from the node that still host a VM of the network, but the broadcast entry is not removed.

Before :
# bridge fdb show dev vxlan-1001
00:00:00:44:44:44 dst 192.168.254.74 self permanent
00:00:00:00:00:00 dst 192.168.254.74 self permanent
52:5a:84:bf:fe:23 vlan 0 permanent

after :
00:00:00:00:00:00 dst 192.168.254.74 self permanent
52:5a:84:bf:fe:23 vlan 0 permanent

    l2-population : send flooding entries when the last port goes down

    Delete port used to call update_port_down to calculate
    its fdb entries during delete_port_precommit. But during
    the pre-commit, the port is still up, so update_port_down
    acts as if there was still one port on the agent, and
    doesn't add flooding entry in its fdb_entries.

    Closes bug #1282141
