hammer2 - Implement depth limit for stack recursion, embedded data fixes

* Implement a procedure call depth limit in hammer2_chain_flush().
  Dirty elements that are too deep are placed on a deferral list and
  then executed at the top-level.  Worst case stack depth is reduced 40:1.

* Fix a bug when transitioning from embedded data to indirect data.
