HAMMER 61B/Many: Stabilization

* Giving the sync_lock's exclusive locks priority over shared locks caused
  a 3-way deadlock, revert to using normal shared locks.

* Move the syncer_lock deeper, closer to the code that actually needs to
  hold but still paying attention to atomicy requirements.  This reduces
  lock contention and improves performance with parallel loads.
