commit f52b83b0b1c40ada38df917973ab719a4a753951 upstream.

Fix afs_lookup() to not clobber the version set on a new dentry by
afs_do_lookup() - especially as it's using the wrong version of the
version (we need to use the one given to us by whatever op the dir
contents correspond to rather than what's in the afs_vnode).

Fixes: 9dd0b82ef530 ("afs: Fix missing dentry data version updating")
