Comment 1 for bug 1590021

This shows up if the API user attempts to reserve an IP and attach it to a name in one step:
    maas session ipaddresses reserve ip_address=10.0.2.98 hostname=test.maas mac=00:11:22:33:44:55

The workaround:
    maas session ipaddresses reserve ip_address=10.0.2.98 mac=00:11:22:33:44:55
    maas session dnsresources create fqdn=test.maas ip_addresses=10.0.2.98
