efi/efivars: Add missing kobject_put() in sysfs entry creation error path
commit d8bd8c6e2cfab8b78b537715255be8d7557791c0 upstream.
The documentation provided by kobject_init_and_add() clearly spells out
the need to call kobject_put() on the kobject if an error is returned.
Add this missing call to the error path.
