pci: layerscape: Adjust the return value when ls_pcie_addr_valid() fails

Browse Source 
When trying to access non-existent/unsupported PCI devices in
ls_pcie_read_config(), when ls_pcie_addr_valid() fails it returns
error code and fills in the result with 0xffffffff manually. But it
really should return zero to upper layer codes.
