mm: workingset: separate shadow unpacking and refault calculation
Per-cgroup thrash detection will need to derive a live memcg from the eviction cookie, and doing that inside unpack_shadow() will get nasty with the reference handling spread over two functions. In preparation, make unpack_shadow() clearly about extracting static data, and let workingset_refault() do all the higher-level handling.
