    hammer2 - Fix indefinite dirty chains due to rename
    
    * Do not call cache_setunresolved() on tnch before calling
      cache_rename().  Doing so prevents cache_rename() from properly
      setting VREF_FINALIZE on the vnode.  Since the deleted inode is
      no longer in the chain hierarchy the related chains can remain
      dirty indefinitely (until the vnode is reused or the filesystem
      is unmounted).
    
    * This fixes inmem dirty chain accounting and 'chnmem' stalls.
