tcp: MD5: Fix IPv6 signatures
Reported by Stefanos Harhalakis; although 2.6.27-rc1 talks to itself using IPv6
TCP MD5 packets just fine, Stefanos noted that tcpdump claimed that the
signatures were invalid.
I broke this in 49a72dfb8814c2d65bd9f8c9c6daf6395a1ec58d ("tcp: Fix MD5
signatures for non-linear skbs"), it was just a typo.
Note that tcpdump will still sometimes claim that the signatures are incorrect.
A patch to tcpdump has been submitted for this[1].
