    Maintenance task: do not change IPv4 ip_port_mappings
    
    IPv4 port mappings would get cleared by format_ip_port_mappings_ipv6(),
    breaking load balancers with health monitors.

Title:
  Restarting octavia breaks IPv4 Load Balancers with health checks

Status in neutron:
  Fix Released

Bug description:
  After implementing IPv6 health check support in change #919229 for the
  ovn-octavia-provider, it appears that the maintenance task is
  inadvertently deleting the `ip_port_mappings` of IPv4 load balancers.
  This issue results in the load balancers ceasing to function upon the
  restart of Octavia.

  I found this as a potential fix for this issue: [Proposed
  Fix](https://review.opendev.org/c/openstack/ovn-octavia-
  provider/+/923196).
