vmxnet3: use correct tcp hdr length when packet is encapsulated 

[ Upstream commit 8a7f280f29a80f6e0798f5d6e07c5dd8726620fe ]

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.
