locking/drm: Fix i915_gem_shrinker_lock() locking
Mike Krinkin reported hangs in the DRM code and bisected it to:
3ab7c086d5ec72585ef0 ("locking/drm: Kill mutex trickery")
Hugh Dickins observed:
"i915_gem_shrinker_lock() is broken: but copy the pattern from
msm_gem_shrinker_lock() and it's okay - patch below."
Pick up the fix in isolation to make sure the bug is fixed, cleanup
patch will follow up.
