sysdev: fix problem with sysdev_class being re-registered
We need to initialize the kobject for a sysdev_class as it could have been recycled (stupid static kobjects...) We also do the same thing in case sysdev devices are being re-registered. Thanks to Balaji Rao <balajirrao@gmail.com> for pointing out the problem.
