evaluate: reject: fix a crash to use tcp reset with network context in bridge

If we use tcp reset with a network protocol that it's not supported, we send an error message. In that case reject.expr is NULL and we have a crash. Therefore we have to use the stmt to indicate that the error comes from the reject.

Please, reword this title and description. I can see you're fixing this by passing the stmt->location instead of the reject expression, which is NULL in this case.

Thanks.
