Toke Høiland-Jørgensen 2b714b607f inet_ecn: Fix endianness of checksum update when setting ECT(1) ...

[ Upstream commit 2867e1eac6 ]

When adding support for propagating ECT(1) marking in IP headers it seems I
suffered from endianness-confusion in the checksum update calculation: In
fact the ECN field is in the *lower* bits of the first 16-bit word of the
IP header when calculating in network byte order. This means that the
addition performed to update the checksum field was wrong; let's fix that.

Fixes: b723748750 ("tunnel: Propagate ECT(1) when decapsulating as recommended by RFC6040")
