This is the third step in bootstrapping the btrfs_find_item interface. The function find_orphan_item(), in orphan.c, is similar to the two functions already replaced by the new interface. It uses two parameters, which are already present in the interface, and is nearly identical to the function brought in in the previous patch. Replace the two calls to find_orphan_item() with calls to btrfs_find_item(), with the defined objectid and type that was used internally by find_orphan_item(), a null path, and a null key. Add a test for a null path to btrfs_find_item, and if it passes, allocate and free the path. Finally, remove find_orphan_item().
