PCI: Allow VPD access for QLogic ISP2722
0d5370d1 ("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. 104daa71 ("PCI: Determine actual VPD size on first access") limits reads to the actual size of VPD, which should prevent these NMIs. 104daa71 was merged *before* 0d5370d1, but we think the testing that prompted 0d5370d1 ("PCI: Prevent VPD access for QLogic ISP2722") was done with a kernel that lacked 104daa71. See [1, 2]. Remove the quirk added by 0d5370d1 ("PCI: Prevent VPD access for QLogic ISP2722") so customers can read the HBA VPD.
