duplicated comments on get_relation_constraints

hi.

in plancat.c, function: get_relation_constraints

```
for (i = 0; i < num_check; i++)
{
Node *cexpr;
/*
* If this constraint hasn't been fully validated yet, we must
* ignore it here. Also ignore if NO INHERIT and we weren't told
* that that's safe.
*/
if (!constr->check[i].ccvalid)
continue;

/*
* NOT ENFORCED constraints are always marked as invalid, which
* should have been ignored.
*/
Assert(constr->check[i].ccenforced);

/*
* Also ignore if NO INHERIT and we weren't told that that's safe.
*/
if (constr->check[i].ccnoinherit && !include_noinherit)
continue;
}
``

The first "Also ignore if NO INHERIT and we weren't told that that's
safe." is duplicated,
also it's in the wrong place?
The second one is fine.
