ocfs2: fix error handling when creating debugfs root in ocfs2_init()
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. Coverity id: 1227009.
