ovn-trace: need to read latest data when using daemon mode

When logical flow changed in SB, the result that ovn-trace using daemon mode evaluate is previous. Because the data from db just is read once when ovn-trace startup. But the daemon mode is not adapted. So we need to keep latest data from SB when ovn-trace use daemon mode. Signed-off-by: Jun Gu <[email protected]>
