Subject: ocfs2: fix crash when initialize filecheck kobj fails

Once s_root is set, genric_shutdown_super() will be called if fill_super()
fails.  That means, we will call ocfs2_dismount_volume() twice in such
case, which can lead to kernel crash.  Fix this issue by initializing
filecheck kobj before setting s_root.
