net/mlx5e: Default to Striding RQ when not conflicting with CQE compression

CQE compression is turned on by default on slow pci systems to help
reduce the load on pci.
In this case, Striding RQ was turned off as CQEs of packets that span
several strides were not compressed, significantly reducing the compression
effectiveness.
This issue does not exist when using the newer mini_cqe format "stride_index".
Hence, allow defaulting to Striding RQ in this case.
