Generated array field unmarshalling handles errors incorrectly for input types

[trotterdylan]

Expected Behaviour

If any element in an array field fails to unmarshal in an input type, it should be reported to clients as an error.

Actual Behavior

If an error occurs unmarshalling any of the array elements but the last, the error is ignored.

Minimal graphql.schema and models to reproduce

input Foo {
    dateAnswers: [Date!]
}

And the generated code:

			it.DateAnswers = make([]model.Date, len(rawIf1))
			for idx1 := range rawIf1 {
				err = (&it.DateAnswers[idx1]).UnmarshalGQL(rawIf1[idx1])
			}
			if err != nil {
				return it, err
			}

The error check should be inside the loop, not done at the end.

Looks like this has already been fixed on next.
