device: Ensure we have sysfs path before comparing.
In some cases we do not have a udev device when setting up a unit (certainly the code gracefully handles this). However, we do then go on to compare the path via path_equal which will assert if a null value is passed in. See https://bugs.mageia.org/show_bug.cgi?id=17766 Not sure if this is the correct fix, but it avoids the crash
