[Impact]
A vulnerability has found in ipv6 implementation at net/ipv6/raw.c: the
IPV6_CHECKSUM offset is not calculated correctly because it does not exclude
an extension header. This error could lead to NULL pointer dereference, which
could be exploited to cause a denial of service.

[Backport]
It is a clean cherry pick.

[Test]
Compile and boot tested.

[Potential Regression]
Expecting low risk of regression as the commit does not change much but adding
an extra layer of conditional calculation.
