net/mlx5e: kTLS, Fix progress params context WQE layout

The TLS progress params context WQE should not include an
Eth segment, drop it.
In addition, align the tls_progress_params layout with the
HW specification document:
- fix the tisn field name.
- remove the valid bit.

Fixes: a12ff35e ("net/mlx5: Introduce TLS TX offload hardware bits and structures")
Fixes: d2ead1f3 ("net/mlx5e: Add kTLS TX HW offload support")
