    hammer2 - Fix panic on corrupt root inode on mount
    
    * If the root inode is corrupt at mount time H2 was panicing
      instead of cleanly aborting.  Fixed by adding missing initialization.
    
    * This case can occur when the device is partially overwritten by
      a dd or another filesystem.  Redundant volume headers may still alow
      H2 to find one, but the iroot might reside at a lower block number and
      already have been blown away.
