[PATCH rdma-next 07/23] RDMA/mlx5: Derive mlx5_ib_adversarial_mode global from mlx5_core adversarial API

[Yishai Hadas <yishaih@nvidia.com>]

Use the mlx5_core mlx5_is_adversarial() exported API to set a
module-level static bool mlx5_ib_adversarial_mode at init time,
instead of a per-device bit field. This avoids propagating the flag
through every mlx5_ib_dev pointer and makes the module-wide policy
clear at the call sites.
