    ML2: update port's status to DOWN if its binding info has changed
    
    This fixes the problem that when two or more ports in a network
    are migrated to a host that did not previously have any ports in
    the same network, the new host is sometimes not told about the
    IP/MAC addresses of all the other ports in the network. In other
    words, initial L2population does not work, for the new host.
    
    This is because the l2pop mechanism driver only sends catch-up
    information to the host when it thinks it is dealing with the first
    active port on that host; and currently, when multiple ports are
    migrated to a new host, there is always more than one active port so
    the condition above is never triggered.
    
    The fix is for the ML2 plugin to set a port's status to DOWN when
    its binding info changes.
    
    This patch also fixes the bug when nova thinks it should not wait
    for any events from neutron because all ports are already active.
