     Purpose
     =======
        ilu_ssnode_dfs() - Determine the union of the row structures of those
        columns within the relaxed snode.
        Note: The relaxed snodes are leaves of the supernodal etree, therefore,
        the portion outside the rectangular supernode must be zero.

     Return value
     ============
         0   success;
        >0   number of bytes allocated when run out of memory.
