Subject: [PATCH rdma-next] net/mlx5: Use flow counter pointer as input to the query function
This allows to un-expose the details of struct mlx5_fc and keep
it internal to the core driver as it used to be.

Jason,
As you asked, I am sending a fixup in case you intend to apply
V2 of the flow counter series [1], if there's going to be V3,
Leon, please apply it from the begining.
Or.
