VFS: move BUG_ON test for symlink nd->depth after current->link_count test
This solves a serious VFS-level bug in nested_symlink (which was
rewritten from do_follow_link), and follows the order of depth tests
that existed before.
The bug triggers a BUG_ON in fs/namei.c:1381, when running racer with
symlink and rename ops.
