[net-next 08/14] net/mlx5: Improve naming of pci function vectors

[Saeed Mahameed <saeed@kernel.org>]

From: Eli Cohen <elic@nvidia.com>

The variable pf_vec is used to denote the number of vectors required for
the pci function's own use. To avoid confusion interpreting pf as
physical function, change the name to pcif_vec.

Same reasoning goes for pf_pool which is really pci function pool.
