Title:
  network-ip-availabilities' result is not correct when the subnet has
  no allocation-pool

Status in neutron:
  Opinion

Bug description:
  Rocky & maybe master:
  I create a network and a subnet.
  Then, I update the subnet to no-allocation-pool
   openstack subnet set 0f4d5c95-879d-4b2a-90d0-350e09375f80 --no-allocation-pool

  Next,I check the availability ips of the network:
    openstack ip availability show 440453b6-d5be-47a8-abed-df7c491e6501

  But I can't create port in the network:
    openstack port create test --network 440453b6-d5be-47a8-abed-df7c491e6501
  {"NeutronError": {"message": "No more IP addresses available on network 440453b6-d5be-47a8-abed-df7c491e6501.", "type": "IpAddressGenerationFailure", "detail": ""}}
