qvm-prefs can't set netvm to none.

[Selenog]

Qubes OS version:

'R4.0-rc2'

Affected TemplateVMs:

Any

---

Steps to reproduce the behavior:

qvm-prefs --set sys-firewall netvm none

Expected behavior:

Configure sys-firewall (or any other VM) to have no netvm.

Actual behavior:

qubesadmin.exc.QubesValueError: VM name cannot be 'none' nor 'default'

General notes:

Seems like the changes related to #3002 made it impossible to set the netvm property to "none". Maybe add a --clear option or --none to qvm-prefs.

"qvm-prefs --default sys-firewall netvm" sets it to it's default which isn't always none

Use empty string (qvm-prefs sys-firewall netvm ""). See man qvm-prefs for details.
