Instead of a if condition with a line split, use the usual error
handling pattern with a separate variable to improve readability.

pci_generic_config_read32() already returns either PCIBIOS_SUCCESSFUL
or PCIBIOS_DEVICE_NOT_FOUND so it is enough to simply return its
return value when ret != PCIBIOS_SUCCESSFUL.

No functional changes intended.
