Subject: [PATCH 4.4 253/342] IB/mlx5: Expose correct maximum number of CQE capacity

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

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

From: Leon Romanovsky <leonro@...lanox.com>

commit 9f17768611ebf81dfac69948dd12622b6f2e45fc upstream.

Maximum number of EQE capacity per CQ was mistakenly exposed
as CQE. Fix that.

Fixes: 938fe83c8dcb ("net/mlx5_core: New device capabilities handling")
