net/mlx5: HWS, Fix error message in mlx5hws_cmd_generate_wqe

This adds the missing trailing newline to the error message printed when
the generate WQE command fails in the HWS send path.

[Severity: Low]
This isn't a code bug, but does the subject point at the right function?
The only change is in hws_send_wqe_fw() in
drivers/net/ethernet/mellanox/mlx5/core/steering/hws/send.c, which is the
caller of mlx5hws_cmd_generate_wqe():

send_wqe:
	ret = mlx5hws_cmd_generate_wqe(mdev, &attr, &cqe);
	if (ret) {
		mlx5_core_err(mdev, "Failed to write WQE using command\n");
		return ret;
	}

mlx5hws_cmd_generate_wqe() itself lives in hws/cmd.c and both of its error
prints already end with '\n':

	ret = mlx5_cmd_exec(mdev, in, sizeof(in), out, sizeof(out));
	if (ret) {
		mlx5_core_err(mdev, "Failed to write GTA WQE using FW\n");
		return ret;
	}

	status = MLX5_GET(generate_wqe_out, out, status);
	if (status) {
		mlx5_core_err(mdev, "Invalid FW CQE status %d\n", status);
		return -EINVAL;
	}

Would something like "net/mlx5: HWS, Add missing newline to error message in
hws_send_wqe_fw" be more accurate, so that someone grepping cmd.c for the
quoted string is not sent to the wrong place?
