[PATCH] IB/mlx5: Expose correct maximum number of CQE capacity

[PATCH] IB/mlx5: Expose correct maximum number of CQE capacity

[Leon Romanovsky]

From: Leon Romanovsky <leonro-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

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

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