pci: layerscape: Adjust the return value when ls_pcie_addr_valid() fails
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. Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
