net/mlx5: Enable setting hairpin queue size

Browse Source 
Allow to specify the size of the hairpin queues along with the
packet buffer data size from the core setup code.

If the driver doesn't provide this, the FW applies proper value that
matches the provided data size and a FW chosen RQ stride size.
