[PATCH 2/2] livepatch: Use correct kobject cleanup function

["Tobin C. Harding" <tobin@kernel.org>]

The correct cleanup function after a call to kobject_init_and_add() has
succeeded is kobject_del() _not_ kobject_put().  kobject_del() calls
kobject_put().

Use correct cleanup function when removing a kobject.
