kib 82f9c275c4 NFSv4 client tracks opens, and the track records are only dropped when
the vnode is inactivated.  This contradicts with the nullfs caching
which keeps upper vnode around, as consequence keeping the use
reference to lower vnode.

Add a filesystem flag to request nullfs to not cache when mounted over
that filesystem, and set the flag for nfs v4 mounts.
