Ilpo Järvinen b6b896c2fd PCI: cpqphp: Fix PCIBIOS_* return value confusion 
[ Upstream commit e2226dbc4a ]

Code in and related to PCI_RefinedAccessConfig() has three types of return
type confusion:

 - PCI_RefinedAccessConfig() tests pci_bus_read_config_dword() return value
   against -1.

 - PCI_RefinedAccessConfig() returns both -1 and PCIBIOS_* return codes.

 - Callers of PCI_RefinedAccessConfig() only test for -1.

Make PCI_RefinedAccessConfig() return PCIBIOS_* codes consistently and
adapt callers accordingly.

Fixes: 1da177e4c3 ("Linux-2.6.12-rc2")
