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

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

From: Eyal Perry <eyalpe@xxxxxxxxxxxx>

[ Upstream commit 83d3459a5928f18c9344683e31bc2a7c3c25562a ]

Carrying out PCI speed/width checks through pcie_get_minimum_link()
on VFs yield wrong results, so remove them.

Fixes: b912b2f ('net/mlx4_core: Warn if device doesn't have enough PCI bandwidth')
