ocfs2: fix error path kobject memory leak
If a call to kobject_init_and_add() fails we should call kobject_put() otherwise we leak memory. Add call to kobject_put() in the error path of call to kobject_init_and_add(). Please note, this has the side effect that the release method is called if kobject_init_and_add() fails. Link: http://lkml.kernel.org/r/20190513033458.2824-1-tobin@kernel.org Signed-off-by: Tobin C.
