PATCH: IPSecv6 in tunnel won't work with ext hdrs

I noticed that using extensions headers along with IPsecv6 tunnel mode did
not work in 2.5.73 + patch-2.5.73-bk3. The following patch
checks "nexthdr" instead of "iph->nexthdr" which could be an
extension header. I tested this with tunnel mode and transport mode
with and without extension headers and it worked ok.

Let me know if it is ok.
