udev: fix segfault with android rndis
The android gadget driver for network tethering over rndis somehow has a parent device with a null subsystem. Probably this is bug in android driver, but it is easy enough to make systemd/udev behave gracefully and not segfault. And this will help for making linux distros with systemd (like fedora) work on android devices.
