PCI: Prevent VPD access for QLogic ISP2722

commit 0d5370d1 upstream.

QLogic ISP2722-based 16/32Gb Fibre Channel to PCIe Adapter has the VPD
access issue too, while read the common pci-sysfs access interface shown as

 /sys/devices/pci0000:00/0000:00:03.2/0000:0b:00.0/vpd

with simple 'cat' could cause system hang and panic:

  Kernel panic - not syncing: An NMI occurred. Depending on your system the reason for the NMI is logged in any one of the following resources:
  1. Integrated Management Log (IML)
  2. OA Syslog
  3. OA Forward Progress Log
  4. iLO Event Log

So blacklist the access to its VPD.
