vmxnet3: correctly report csum_level for encapsulated packet
Commit dacce2be3312 ("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.
