[Intel-gfx] [PATCH] drm/i915/selftests: mark huge_gem_object as not shrinkable

[Matthew Auld]

It looks like the callers expect a non-volatile object, but it looks the
shrinker will discard the object pages anyway, thinking that the pages
can be swapped out if the object is marked as WILLNEED. If that's true
then it might be better to mark it as volatile and fix the callers
instead, but on the other hand huge_gem_objects are fairly unique in
that they duplicate pages for the backing store, so maybe shrinking is
not that applicable.
