[PATCH net-next V3 1/5] net/mlx5e: Count full skb length in TSO byte counters

The tso_bytes and tso_inner_bytes counters currently subtract the header
length from skb->len, counting only the payload. This is confusing and
doesn't align with the behavior of other _bytes counters in the driver.

Report the full skb length to align with this expectation.

This also makes our behavior consistent with the netdev stats API and
virtio spec definition.
