    DVR: Don't clean snat-ns of DVR HA router when fullsync

    Since [1], when the l3 agent does fullsync, for every router, it calls
    ensure_snat_cleanup depending on whether the agent is dvr_snat or not.
    However, DVR+HA routers always have snat namespaces on dvr_snat agents
    holding themselves for keepalived. Therefore, the cleanup call is
    unexpected and will cause a series of issues.

    This patch ensures that snat namespaces of DVR+HA routers will not be
    cleaned when the agent do fullsync.
