Environment

Python version: 3.5.2
NetBox version: 2.2.9
OS: Centos 7

I have got a Netbox-2.2.9 instance installed on a Centos 7 supported by Python-3.5.2.

Description

1. Create a new VM instance.
2. Create an interface and get it attached to the VM.
3. Assign a predefined IP address to the interface.
4. Mark the IP address as "primary_ipv4" in the VM's entries.

In this case, there is no way to withdraw the "primary_ipv4" through web UI, and as a workaround, I did it by leveraging the relative API.
Like so:

curl -X PATCH -k --header 'Content-Type: application/json' -H "Authorization: Token 1234" -d '{"primary_ip4": null}' https://netbox.test.lan/api/virtualization/virtual-machines/8539/

Confirming the issue is fixed in v2.2.10.
Thanks @jeremystretch
