Yi Li b918c43021 ocfs2: fix panic due to ocfs2_wq is null 
mount.ocfs2 failed when reading ocfs2 filesystem superblock encounters
an error.  ocfs2_initialize_super() returns before allocating ocfs2_wq.
ocfs2_dismount_volume() triggers the following panic.

  Oct 15 16:09:27 cnwarekv-205120 kernel: On-disk corruption discovered.Please run fsck.ocfs2 once the filesystem is unmounted.
