    Remove leftover OVN LB HM port upon deletion of a member

    When a load balancer pool has a Health Monitor associated with it,
    an OVN LB Health Monitor port is created for each backend member
    subnet added.

    When removing backend members, the OVN LB Health Monitor port is
    cleaned up only if no more members are associated with the Health
    Monitor pool. However, this assumption is incorrect. This patch
    corrects this behavior by checking instead if there are more members
    from the same subnet associated with the pool. It ensures that the
    OVN LB Health Monitor port is deleted only when the last member from
    the subnet is deleted. If the port is being used by another different
    LB Health Monitor, `_clean_up_hm_port` will handle it.
