Vlad Yasevich e87a468eb9 ipv6: Fix udp checksums with raw sockets 
It was reported that trancerout6 would cause
a kernel to crash when trying to compute checksums
on raw UDP packets.  The cause was the check in
__ip6_append_data that would attempt to use
partial checksums on the packet.  However,
raw sockets do not initialize partial checksum
fields so partial checksums can't be used.

Solve this the same way IPv4 does it.  raw sockets
pass transhdrlen value of 0 to ip_append_data which
causes the checksum to be computed in software.  Use
the same check in ip6_append_data (check transhdrlen).
