When I remove only the kvm-intel module without removing the kvm module
itself, I get an error saying that a kobject is trying to be
reinitialized. Its because of the fact that kvm reuses a kobject in
kvm_init when calling sysdev_register.

This patch fixes kobject_cleanup by marking the kobject as uninitialized
when we cleanup to allow kobjects to be reused.
