    hammer2 - Fix CHECK fail path that might mangle an inode in-memory
    
    * Allowing the wrong inode block to be entered in-memory can result in
      massive filesystem confusion.
    
    * Add a sanity check in hammer2_chain_inode_find() to validate that
      the inode field in an on-media inode matches the inode number we are
      trying to look up.  This case is not supposed to happen, but it did on
      grok's /build5 partition (likely due to a bulkfree early-termination
      issue which is now being looked at).
    
      If this test fails, we simulate a CRC CHECK failure.
    
    * Remove hammer2_cluster_resolve() (it was replaced by hammer2_cluster_check()).
