Not process security group for none active ports
We recently met an issue during VM live migration:
1. nova starts live migration
2. plug ports on new host
3. neutron-ovs-agent starts to process the port,
but the port is in 'added' and 'updated' set
at the same time.
4. because nova still not activate the destination
port binding, so there is no local vlan for
this port.
Then, ovs-agent met errors:
Error while processing VIF ports: OVSFWTagNotFound:
Cannot get tag for port tap092f38ed-a7 from its other_config: {}
This fix is to remove ports of the
"binding_no_activated_devices" for ``setup_port_filters``.

Title:
[ml2][ovs] ports without local vlan tag are processed on openflow

Fix Released
Bug description:
We recently met an issue during VM live migration:
1. nova starts live migration
2. plug ports on new host
3. neutron-ovs-agent starts to process the port, but the port is in 'added'
and 'updated' set at the same time.

Then, ovs-agent met errors:

tap092f38ed-a7 from its other_config: {}
Such exception will finally hit rpc_loop try-catch block, a full sync
for all ports will be run. This will cause the new port consume a long
time to finish the process. Users will have bad experiences of long
time packet loss.
A fix should be added for ``setup_port_filters`` to remove ports of
the "binding_no_activated_devices".
