devres: WARN() and return, don't crash on device_del() of uninitialized device
I just debugged an obscure crash caused by a device_del() of a all NULL'd out struct device (in usb-serial) and found that a patch like this one would have saved me time (in addition to improved chances of a bug report from users hitting similar driver bugs).
