    DVR: Fix unbound fip port migration to bound port

    With the current change in allowing the unbound fip
    to be associated with the snat node, we are seeing
    that all floating IPs that are associated with an
    unbound port are created at the snat node.
    This is also applicable for floating IPs that are
    created just before associating the port to a VM.
    We have seen such scenarios in the test cases.

    This is the right behavior as per design. But when
    the port is bound to a host, the floating IP should
    be migrated to the respective host.

    This patch fixes the issue by sending notification to
    the respective node, when the port is bound and also
    clear the fip from the snat node.
