drm/xe: Clear xe->display when no longer valid

Browse Source 
Don't leave a stale xe->display pointer hanging around after
the display driver has been torn down.

While xe shouldn't hit the display reset related issue that
affects i915, leaving stale pointer floating around still
seems like a bad idea.
