[PATCH 5.4 64/93] IB/mlx5: Introduce and use mlx5_core_is_vf()

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

5.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Parav Pandit <parav@mellanox.com>

[ Upstream commit e53a9d26cf80565cfb7172fc52a0dfac73613a0f ]

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.
