ipv6: Fix exthdrs offload registration.
[ Upstream commit d2d273ffabd315eecefce21a4391d44b6e156b73 ]
Without this fix, ipv6_exthdrs_offload_init doesn't register IPPROTO_DSTOPTS
offload, but returns 0 (as the IPPROTO_ROUTING registration actually succeeds).
This then causes the ipv6_gso_segment to drop IPv6 packets with IPPROTO_DSTOPTS
header.
The issue detected and the fix verified by running MS HCK Offload LSO test on
top of QEMU Windows guests, as this test sends IPv6 packets with
IPPROTO_DSTOPTS.
