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,

Closes: https://gitlab.freedesktop.org/drm/intel/issues/1392
Fixes: ebece7539242 ("drm/i915: Keep timeline HWSP allocated until idle across the system")
