[dpdk-dev] [PATCH] net/mlx5: fix 32-bit build

This is to fix the error:
  ```

  of type 'long unsigned int', but argument 5 has type 'off_t {aka long
  long int}' [-Werror=format=]

Which reproduces with gcc (Ubuntu 7.4.0-1ubuntu1~18.04.1) 7.4.0.

Minor nitpick:
You don't need empty string at the end of the format.

Applied to dpdk-next-net/master, thanks.

(empty string at the end removed while merging)
