vlrureclaim: only skip vnode with resident pages if it own the pages
Nullfs vnode which shares vm_object and pages with the lower vnode should
not be exempt from the reclaim just because lower vnode cached a lot.
Their reclamation is actually very cheap and should be preferred over
real fs vnodes, but this change is already useful.
