: Fix ECN target TCP marking

Hi Dave,

these patches fix HW checksum handling in the ECN and TCPMSS target. The second and third patch don't apply to both net-2.6 and net-2.6.14 because of the nfcache removal and renaming of skb_ip_make_writable, I've attached one patch for each tree.

[NETFILTER]: Fix ECN target TCP marking

An incorrect check made it bail out before doing anything.
