    DVR: Cleanup ml2 dvr portbindings on migration

    When a DVR router is migrated from distributed to
    centralized, we are unbinding the router from the
    agents, but the ml2 distributed portbindings for
    the router port still remains intact.

    This patch will fix the issue by deleting the
    binding entry for multiple hosts.
