Chris Wilson 8ea6bb8e4d drm/i915/gt: Close race between cacheline_retire and free
If the cacheline may still be busy, atomically mark it for future
release, and only if we can determine that it will never be used again,
immediately free it.

Closes: https://gitlab.freedesktop.org/drm/intel/issues/1392
Fixes: ebece75392 ("drm/i915: Keep timeline HWSP allocated until idle across the system")
