Subject: ocfs2: ocfs2_prep_new_orphaned_file() should return ret
If an error occurs, for example an EIO in __ocfs2_prepare_orphan_dir,
ocfs2_prep_new_orphaned_file will release the inode_ac, then when the
caller of ocfs2_prep_new_orphaned_file gets a 0 return, it will refer to a
NULL ocfs2_alloc_context struct in the following functions. A kernel
panic happens.
