afs: Fix afs_lookup() to not clobber the version on a new dentry
commitf52b83b0b1
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:9dd0b82ef5
