Set |bn->neg| to zero in |bn_set_words|.

If the values of any of the coordinates in the output point |r| were
negative during nistz256 multiplication, then the calls to
|bn_set_word| would result in the wrong coordinates being returned
(the negatives of the correct coordinates would be returned instead).
Fix that.
