vmxnet3: correctly report csum_level for encapsulated packet 



Commit dacce2be ("vmxnet3: add geneve and vxlan tunnel offload
support") added support for encapsulation offload. However, the
pathc did not report correctly the csum_level for encapsulated packet.

This patch fixes this issue by reporting correct csum level for the
encapsulated packet.
