`errors.As` usage is broken as of v2.5.9

[vito]

What happened?

Hiya - we use errors.As here and noticed after bumping to v2.5.9 the error value is just a typed nil.

It looks like this broke with this change because now it's only updating the local var within the As implementation.

What did you expect?

The provided argument is already a pointer (and has to be otherwise you get linting errors), so it should just update it in-place.

Minimal graphql.schema and models to reproduce
