vmxnet3: use correct hdr reference when packet is encapsulated
'Commit dacce2be3312 ("vmxnet3: add geneve and vxlan tunnel offload support")' added support for encapsulation offload. However, while preparing inner tso packet, it uses reference to outer ip headers. This patch fixes this issue by using correct reference for inner headers.
