Commit Fixes: 8c36786c8198 ("btrfs-progs: print-tree: Print offset as tree objectid for ROOT_ITEM") changes how we translate offset of ROOT_ITEM.
However the fact is, even for ROOT_ITEM, we have different meaning of offset. For tree reloc tree, it's indeed subvolume id. But for other trees, it's the transid of when it's created. Fix it.
