Subject: IB/mlx5: Introduce and use mlx5_core_is_vf()
Patch-mainline: v5.5-rc1
Git-commit: e53a9d26cf80565cfb7172fc52a0dfac73613a0f
References: jsc#SLE-8446
Instead of deciding a given device is virtual function or
not based on a device is PF or not, use already defined
MLX5_COREDEV_VF by introducing an helper API mlx5_core_is_vf().
This enables to clearly identify PF, VF and non virtual functions.
