[PATCH] drm/i915/selftests: prefer the create_user helper

[Matthew Auld <matthew.auld@xxxxxxxxx>]

No need to hand roll the set_placements stuff, now that that we have a
helper for this. Also no need to handle the -ENODEV case here, since
NULL mr implies missing device support, where the for_each_memory_region
helper will always skip over such regions.
