This is just paranoia. In all these cases we don't really care about the trailing NUL byte. But if there's space for it dns_label_unescape() is going to insert it, and that's a good safety strategy. This is a follow-up to c29c3adefa8cd859f8cb87d9ad62f3d77b7cd102 which fixed an actual bug, unlike this commit, which is just paranoia.
