Subject: [net-next V3 03/14] net/mlx5: Simplify mlx5_sriov_is_enabled() by using pci core API

From: Parav Pandit <parav@...lanox.com>

It is desired to get rid of num_vfs stored inside mlx5_core_sriov to
safely support vports more than vfs.
To reduce dependency on mlx5_core_sriov num_vfs, start using
pci_num_vf() from pci core.
