If the caller says that he doesn't want to evict any other faulting
vma, honour that flag. The logic was used in evict_something, but not
the more specific evict_for_node, now being used as a preliminary probe
since commit
606fec956c0e ("drm/i915: Prefer random replacement before
eviction search").
Fixes: 606fec956c0e ("drm/i915: Prefer random replacement before eviction search")
Fixes: 821188778b9b ("drm/i915: Choose not to evict faultable objects from the GGTT")
