    hammer2 - Fix inode destroy panic
    
    * Fix a race in hammer2_inode_xop_destroy() when deleting an inode chain.
      The parent can be ripped out from under the code before it gets both
      parent and chain locked, resulting in an assertion in hammer2_chain_delete().
    
      Properly test the linkage and retry if the parent changes.
