[PATCH] ocfs2: Fix error path kobject memory leak

[Tobin C. Harding]

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.

Is it ok to send patches during the merge window?

Applies on top of Linus' mainline tag: v5.1

Happy to rebase if there are conflicts.

thanks,
Tobin.
