Revert "f2fs: fix to do sanity check on direct node in truncate_dnode()"
This reverts commit a78a8bcdc26de5ef3a0ee27c9c6c512e54a6051c which is
commit a6ec83786ab9f13f25fb18166dee908845713a95 upstream.
Something is currently broken in the f2fs code, Guenter has reported
boot problems with it for a few releases now, so revert the most recent
f2fs changes in the hope to get this back to a working filesystem.
