Subject: [PATCH 2/3] bridge: Use correct cleanup function

The correct cleanup function if a call to kobject_init_and_add() has
returned _successfully_ is kobject_del().  kobject_put() is used if the
call to kobject_init_and_add() fails.  kobject_del() calls kobject_put().

Use correct cleanup function in error path.
