    kernel - Fix unnecessary ucred duplication
    
    * Fix unnecessary ucred replication.  This is not a memory leak, but it
      is annoying.
    
    * Replicated ucreds can build-up in the system (up to maxvnodes) due to
      to unlinked files.
    
    * Fix by flagging unlinked files in np->n_flag and immediately recycling
      the related vnode in the inactive code if it has been flagged for
      removal.
