vmm: Only allow removal of specific types of virtio device

Browse Source 
Now that all virtio devices are assigned with identifiers, they could
all be removed from the VM. This is not something that we want to allow
because it does not make sense for some devices. That's why based on the
device type, we remove the device or we return an error to the user.
