drm/xe: Do not attempt to bootstrap VF in execlists mode

Browse Source 
[ Upstream commit f3b59457808f61d88178b0afa67cbd017d7ce79e ]

It was mentioned in a review that there is a possibility of choosing
to load the module with VF in execlists mode.

Of course this doesn't work, just bomb out as hard as possible.
