[Bug 1533313] [NEW] _get_dvr_sync_data should be optimized for 'dvr' mode agent

 

Public bug reported:

Per patch https://review.openstack.org/#/c/239908 for bug "Function
sync_routers always call _get_dvr_sync_data in ha scenario", it will
make _get_dvr_sync_data only be called for agent in 'dvr'/'dvr_snat'
mode, and avoid additional floatingip processing for legacy/HA router
than DVR router.

But for DVR scenario, only query floatingips associated ports on given
host should be necessary, and no need to do additional filter processing
which should be done sql.

** Affects: neutron
