Subject: [PATCH 4.18 040/145] IB/mlx5: Honor cnt_set_id_valid flag instead of set_id

4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Parav Pandit <parav@...lanox.com>

commit 921c0f5ba58e4064deb18b4985a202508fc5527f upstream.

It is incorrect to depend on set_id value to know if counters were
allocated or not. set_id_valid field is set to true when counters
were allocated. Therefore, use set_id_valid while deciding to
free counters.
