{net, RDMA}/mlx5: Fix override of log_max_qp by other device
mlx5_core_dev holds pointer to static profile, hence when the
log_max_qp of the profile is override by some device, then it
effect all other mlx5 devices that share the same profile.
Fix it by having a profile instance for every mlx5 device.
Fixes: 883371c453b9 ("net/mlx5: Check FW limitations on log_max_qp before setting it")
