btrfs-progs: print-tree: Do correct offset output for ROOT_ITEM
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.
