    Check SG members instead of ports to skip flow update
    
    Security group can have a state of empty ports but non-empty members. So
    we need skip the flow update only when members dict is empty.

Title:
  Neutron remote security group does not work

Status in neutron:
  Fix Released

Bug description:
  Steps to reproduce the issue using Neutron Rocky with OVS:

  # create bastion-sec-grp to allow ssh from anywhere
  openstack security group create bastion-sec-grp
  openstack security group rule create --ethertype=IPv4 --protocol tcp --remote-ip 0.0.0.0/0 --ingress --dst-port=22 bastion-sec-grp

  # create application-sec-grp
  openstack security group create application-sec-grp

  # Allow ssh to egress from the bastion group to the application group
  openstack security group rule create --ethertype=IPv4 --protocol tcp --remote-group application-sec-grp --egress --dst-port=22 bastion-sec-grp

  # Allow ssh to ingress to the application group from the bastion group
  openstack security group rule create --ethertype=IPv4 --protocol tcp --remote-group bastion-sec-grp --ingress --dst-port=22 application-sec-grp

  # create servers and associate with security groups
  openstack server create --wait --image rhel7 --flavor small --security-group bastion-sec-grp bastion-server
  openstack server create --wait --image rhel7 --flavor small --security-group application-sec-grp application-server

  After boot, bastion-server and application-server are landed on
  different HVs and we can ssh to bastion-server but cannot ssh to
  application-server from there. Neutron debug log from application-
  server's HV shows:

  2020-02-05 22:57:05,825 DEBUG
  [neutron.agent.linux.openvswitch_firewall.firewall]
  /opt/openstack/venv/neutron/lib/python2.7/site-
  packages/neutron/agent/linux/openvswitch_firewall/firewall.py:_build_addr_conj_id_map:297
  No member for SG <BASTION_SEC_GRP_ID>

  
  Suspect this is related to: https://bugs.launchpad.net/neutron/+bug/1854131 and after reverting the change https://review.opendev.org/#/c/696976/ locally then remote security group started to work again.
