[PATCH 2/5] net/mlx5: add mlx5_hw_create_mirror function.

[Gregory Etelson <getelson@nvidia.com>]

The new mlx5_hw_create_mirror() function separates existing HWS mirror
functionality into mirror action creation and indirect list
handle creation.

The new mirror creation function will be used in non-template SAMPLE
action implementation.
