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.
