[PATCH] cpuidle: Fix several reference count leaks.

[wu000273]

From: Qiushi Wu <wu000...@umn.edu>

kobject_init_and_add() takes reference even when it fails.
If this function returns an error, kobject_put() must be called to
properly clean up the memory associated with the object. Previous
commit "b8eb718348b8" fixed a similar problem.
