net/mlx5: Adjust log_max_qp to be 18 at most 



The cited commit limited log_max_qp to be 17 due to FW capabilities.
Recently, it turned out that there are old FW versions that supported
more than 17, so the cited commit caused a degradation.

Thus, set the maximum log_max_qp back to 18 as it was before the
cited commit.
