[PATCH] EDAC: Fix some refcount leaks

[Miaoqian Lin]

kobject_init_and_add() takes reference even when it fails.
According to the doc of kobject_init_and_add()

   If this function returns an error, kobject_put() must be called to
   properly clean up the memory associated with the object.

Fix this by calling kobject_put() when kobject_init_and_add() fails.
