Subject: IB/mlx5: Fix entries checks in mlx5_ib_create_cq
From: Noa Osherovich <noaos@mellanox.com>
commit 9ea578528656e191c1097798a771ff08bab6f323 upstream.
Number of entries shouldn't be greater than the device's max
capability. This should be checked before rounding the entries number
to power of two.
Fixes: 51ee86a4af639 ('IB/mlx5: Fix check of number of entries...')
