ls: fix one stupid performance bug

No point doing a stat on each node when we don't actually need it !

We should chdir into the directory before doing the stats on the short path.
That avoids all the name walking overhead and thrash. Likewise it might be
sensible to stat in inode order and batched, but that may cost more than
the saving !
