[ovn]router_interface port probability cannot be up

[ZhouHeng]

I have en environment, with 5 neutron-server(W version), 5 ovn(21.03.1)

When adding an interface to the router, the state of the interface is sometimes down,
and it will not become up after a long time. Restarting the neutron server can become up.

I check logical_switch_port by "ovn-nbctl list logical_switch_port <port-id>", the status
of lsp is up, and the traffic can be forwarded normally.

This should only be a neutron save state problem.

In the past, when creating vm, the ports have been unable to be up, and the reason has not
been found. The phenomenon is the same as that of the router interface.

In the process of adding a routing interface, I wrote a script to listen to logical_switch_port
change, I found: before lsp becomes up=true, lsp's up=[], which is not up=[false], not
matchd LogicalSwitchPortUpdateUpEvent. I don't know why ovn's notification events are
sometimes different, but I think it should be repaired here in neutron

    [ovn]Change LogicalSwitchPortUpdateUpEvent old conditions

    Sometimes when creating ports, the status of logical_switch_port
    changes from [] to [true]. we should be able to deal with this
    situation and ensure that the port is in the active state in neutron.
