EDAC: Fix reference count leaks
BugLink: https://bugs.launchpad.net/bugs/1892822 [ Upstream commit 17ed808a ] When kobject_init_and_add() returns an error, it should be handled because kobject_init_and_add() takes a 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. Therefore, replace calling kfree() and call kobject_put() and add a missing kobject_put() in the edac_device_register_sysfs_main_kobj() error path.
