RDMA/mlx5: Remove not-used cache disable flag
During execution of mlx5_mkey_cache_cleanup(), there is a guarantee
that MR are not registered and/or destroyed. It means that we don't
need newly introduced cache disable flag.
Fixes: 374012b00457 ("RDMA/mlx5: Fix mkey cache possible deadlock on cleanup")
