    hammer2 - Fix inode count statistics
    
    * Fix two inode count statistics bugs related to recent work.
    
      (1) We have to zero out the stats when deleting an indirect block in
          the indirect block collapse case because the underlying children
          will add them back in when they are moved into the prent.  This is
          because we are using the 'trick' of removing the indirect block
          before moving its children to avoid significant code complexity.
    
      (2) inode_count accounting was improperly counting certain DATA records
          as inodes.
