Jon Seymour 4d98a1cf28 tsm: cache: remove unnecessary lock escalation. 
Previously, we needed a write lock on the cache because it was the
only lock we had available to guard updates to entry.values and
entry.needSort.

However, now we have a entry-scoped lock for this purpose, we don't
need the cache write lock for this purpose. Since merged() doesn't
modify the .store or the c.snapshot.sort, there is no need for
a write lock on the cache to protect the cache.

So, we don't need to escalate here - we simply rely on the entry lock
to protect the entries we are iterating over.
