    hammer2 - hardlink stabilization pass
    
    * Fix infinite loop in hammer2_chain_create_indirect() related to the
      case where the key range is the full 64 bits, which can occur when
      invisible hardlink entries are mixed in with normal entries.
    
    * Fix the nlinks count in a couple of places.
    
    * Don't iterate invisibile directory entries.  Lookups of hardlink targets
      by inode number are absolute.  Normal directory entries have a collision
      counter, hardlink targets do not.
