If decode_prefix6() returns a negative number, don't print buf.

If it returns a negative number, it hasn't necessarily filled in buf, so
just return immediately; this is similar to the IPv4 code path, wherein
we just return a negative number, and print nothing, on an error.

This should fix GitHub issue #763.
