PCI: Allow VPD access for QLogic ISP2722

PCI: Allow VPD access for QLogic ISP2722

0790ae0564ab ("PCI: Prevent VPD access for QLogic ISP2722") disabled access
to VPD of the ISP2722-based 16/32Gb Fibre Channel to PCIe Adapter because
reading past the end of the VPD caused NMIs.

d3afef2eae86 ("PCI: Determine actual VPD size on first access") limits
reads to the actual size of VPD, which should prevent these NMIs.

d3afef2eae86 was merged *before* 0790ae0564ab, but we think the testing
that prompted 0790ae0564ab ("PCI: Prevent VPD access for QLogic ISP2722")
was done with a kernel that lacked d3afef2eae86.  See [1, 2].

Remove the quirk added by 0790ae0564ab ("PCI: Prevent VPD access for QLogic
ISP2722") so customers can read the HBA VPD.
