Merge: vmxnet3: correctly report csum_level for encapsulated packet

MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/1847

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2158807

Commit dacce2b ("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.
