 Purpose
 =======
    ilu_csnode_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.
