lib: fix __fdt_parse_region()

If fdt_getprop() returns NULL, this indicates an error. In this case lenp is set to an error code. But even if lenp = 0 we should not continue. If fdt_getprop() returns a wider value than we expect this is a separate error condition. In both cases the device-tree is invalid.
