[PATCH] gfs2: Unregister debugfs on filesystem registration failure

init_gfs2_fs() registers debugfs before registering the GFS2
filesystems. If either filesystem registration fails, the
error path tears down the other resources but leaves debugfs
registered. Call gfs2_unregister_debugfs() from the filesystem
registration failure path.
