ocfs2: fix error handling when creating debugfs root in ocfs2_init()

Browse source 
Error handling if creation of root of debugfs in ocfs2_init() fails is
broken.  Although error code is set we fail to exit ocfs2_init() with
error and thus initialization ends with success.  Later when mounting a
filesystem, ocfs2 debugfs entries end up being created in the root of
debugfs filesystem which is confusing.

Fix the error handling to bail out.
