Preparation of the headers for the hardware offload
misses the outer IPv4 checksum offload.
It results in bad checksum computed by hardware NIC.
This patch fixes the issue by setting the outer IPv4
checksum field to 0.

Not directly related with this patch, but is the function 'rte_net_intel_cksum_flags_prepare()' really Intel specific? I can see sfc & ena are also using this function, should we rename it?
