    nfs_lookup: vn_lock the vnode returned by cache_lookup_raw
    before feeding it to VOP_GETATTR.  it's necessary because the vnode might
    be being cleaned by getcleanvnode.

    it's an instance of more general races between vnode reclaim and
    unlocked VOPs.  however, this one happens somewhat often because it can be
    triggered by getnewvnode rather than revoke.
