main.cte_nonrecursive failed in --embedded (again)

cte_nonrecursive fails in 10.3 in embedded builds like

main.cte_nonrecursive                    w2 [ fail ]

mysqltest: At line 770: query '$q' failed: 1146: Table 'test.cte_i' doesn't exist

The reason is the commit 3afc962 that fixed the bug MDEV-13453. It added this

if (tl->with ||

    (tl->with= tl->select_lex->find_table_def_in_with_clauses(tl)))

  continue; 

to check_grant() function. Which is wrong, privilege checking functions cannot have side-effects (like setting tl->with above) because they are not executed in embedded builds.

For some reason, that I did not look into, this does not fail in 10.2, though.
