drm/i915: Fix up usage of SHRINK_STOP
In commit 81e49f811404f428a9d9a63295a0c267e802fa12 Author: Glauber Costa <[email protected]> Date: Wed Aug 28 10:18:13 2013 +1000 i915: bail out earlier when shrinker cannot acquire mutex SHRINK_STOP was added to tell the core shrinker code to bail out and go to the next shrinker since the i915 shrinker couldn't acquire required locks. But the SHRINK_STOP return code was added to the ->count_objects callback and not the ->scan_objects callback as it should have been, resulting in tons of dmesg noise like shrink_slab: i915_gem_inactive_scan+0x0/0x9c negative objects to delete nr=-xxxxxxxxx Fix discusssed with Dave Chinner.
