This reverts commit f2538f999345405f7d2e1194c0c8efa4e11f7b3a. The patch stopped JFFS2 from being able to mount an existing filesystem with the following errors:

jffs2: error: (77) jffs2_build_inode_fragtree: Add node to tree failed -22 jffs2: error: (77) jffs2_do_read_inode_internal: Failed to build final fragtree for inode #5377: error -22
