btrfs-progs: fi du: don't call lookup_path_rootid for BTRFS_EMPTY_SUBVOL_DIR_OBJECTID
When ino is BTRFS_EMPTY_SUBVOL_DIR_OBJECTID, the item is not referred to
any file-tree. So lookup_path_rootid() doesn't return any meaningful
value.
As was reported, this can be triggered by
$ btrfs sub create test1
$ btrfs sub create test1/test2
$ btrfs sub snap test1 test1.snap
$ btrfs fi du -s test1
Total Exclusive Set shared Filename
0.00B 0.00B 0.00B test1
$ btrfs fi du -s test1.snap
Total Exclusive Set shared Filename
ERROR: cannot check space of 'test1.snap': Inappropriate ioctl for device
