'Commit dacce2be3312 ("vmxnet3: add geneve and vxlan tunnel offload
support")' added support for encapsulation offload. However, while
calculating tcp hdr length, it does not take into account if the
packet is encapsulated or not.

This patch fixes this issue by using correct reference for inner
tcp header.

support")
