ip6_output: fix regression introduced in r358167 for ipv6 fragmentation

When moving the calculations for the optlen into the if (opt) block
which deals with possible extension headers I failed to initialise
unfragpartlen to the ipv6 header length if there were no extension
headers present.  Correct that mistake to make IPv6 fragment length
calculcations work again.
