Restore crud flags if visiting_cte is set

Fixed bug where a CTE of an INSERT/UPDATE/DELETE that also uses RETURNING
could then not be SELECTed from directly, as the internal state of the
compiler would try to treat the outer SELECT as a DELETE statement itself
and access nonexistent state.

Fixes: #5181
Change-Id: Icba76f2148c8344baa1c04bac4ab6c6d24f23072
(cherry picked from commit 7fe400f54632835695f7b98f0c1a54424953dfad)
