udp6: fix encap return code for resubmitting
The commit eb63f2964dbe ("udp6: add missing checks on edumux packet processing") used the same return code convention of the ipv4 counterpart, but ipv6 uses the opposite one: positive values means resubmit. This change addresses the issue, using positive return value for resubmitting. Also update the related comment, which was broken, too.
