Revert "jffs2: Fix possible null-pointer dereferences in jffs2_add_frag_to_fragtree()"
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
Fixes: f2538f999345 ("jffs2: Fix possible null-pointer dereferences...")
