Subject: 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.
