More multi-DC tweaks to MessageCache::load()

* Use hash key volatility to propagate invalidations over DCs
  in addition to memcached->APC instances.
* Make use of stale APC cache due to hash mismatch instead
  of waiting around in some cases. This is similar to the
  TTL expiry and volatility cases.
* Renamed $hashExpired and added some comments for clarity.
