[PATCH 4.9 091/152] PCI: Expand "VPD access disabled" quirk message

[Greg Kroah-Hartman]

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

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

From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

[ Upstream commit 044bc425bb72ffdecfb2a66d50cb1d024ecb96d0 ]

It's not very enlightening to see

  pci 0000:07:00.0: [Firmware Bug]: VPD access disabled

in the dmesg log because there's no clue about what the firmware bug is.
Expand the message to explain why we're disabling VPD.
