If a domain is configured to have an egl-headless display and a virtio video device, virgl will be enabled automatically within the guest, even if the video device is configured with accel3d='no'.
In this case we should explicitly pass 'virgl=off' to qemu.

Reviewed-by: Michal Privoznik <mprivozn@redhat.com> and pushed. Even though I still don't understand what good it is to use egl-headless with accel3d='no'. Can it be used for when I'm passing two video cards? For instance, one <video/> (primary) and then <hostdev/> (secondary) and I want the secondary card (which is a physical card, hence more powerful) to do the rendering? Michal
