    fix get_ha_sync_data_for_host for non-dvr agent

    get_ha_sync_data_for_host will call _get_dvr_sync_data
    even given agent is not in DVR agent_mode.
    _get_dvr_sync_data has additional processing for dvr
    like:
        dvr_router_ids = set(router['id'] for router in routers
                             if is_distributed_router(router))
        floating_ip_port_ids = [fip['port_id'] for fip in floating_ips
                                    if fip['router_id'] in dvr_router_ids]
    which should only work for DVR scenario.

    That will increase neutron-server processing time for
    non-DVR scenario. Adding logic to judge whether given
    agent is in DVR agent_mode, call get_sync_data directly.
