Subject: IB/mlx5: Expose correct maximum number of CQE capacity

From: Leon Romanovsky <[email protected]>

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")
