PCI: handle positive error codes
Callers expect pci_user_{read,write}_config_*() to indicate errors by
returning negative values. Prior to this change, the indicated routines
could return positive error codes (e.g. PCIBIOS_BAD_REGISTER_NUMBER)
which callers would mistakenly interpret as success.
This change converts any non-zero return from the mentioned routines
into unambiguous negative value return codes.
