Environment

Python version: 3.6.6
NetBox version: 2.5.1

Steps to Reproduce

Create a global (w/o site) VLAN, VLAN-Group. You are now able to assign this VLAN to an interface in any site as the VLAN is global. This works fine and as expected.

After that try to create a prefix and assign it to the vlan. This is from the child prefixes view (netbox/ipam/prefixes/1/prefixes/) not possible as this causes an Error 400 after selecting the VLAN-Group or if the Prefix is assigned to a site unselecting the site:

GET /netbox/api/ipam/vlans/?site_id=0&group_id=1&limit=0&brief=1

HTTP 400 Bad Request
Allow: GET, POST, HEAD, OPTIONS
Content-Type: application/json
Vary: Accept

{
"site_id": [
"Select a valid choice. %(value)s is not one of the available choices."
]
}

Expected Behavior

It should be possible to assign a vlan to the prefix if it is global as VLANs/Prefixes cannot be assigned to Regions, nor the Sites are hierarchical.

Observed Behavior

No VLAN can be selected after selecting a global VLAN-Group.
