Public bug reported:
In function 'treat_devices_added_or_updated', port not exist at 'br-int' will
be added into 'skipped_devices', and return to parent function
'process_network_ports', and 'process_network_ports' will remove these ports
from port_info['current'].
If a port updated due to 'sg_member', and the port deleted just in function
'treat_devices_added_or_updated', so the port aded into 'skipped_devices', then
it removed from port_info['current']. When next 'scan_port', the port not in
'registered_ports', so it not added into port_info['removed'], it's chains and
rules will never been removed. These waste chains and rules stay in iptables
util ovs-agent restart or compute node restart.
