xen-pcifront: Handle backend CLOSED without CLOSING

Backend drivers shouldn't transition to CLOSED unless the frontend is
CLOSED.  If a backend does transition to CLOSED too soon then the
frontend may not see the CLOSING state and will not properly shutdown.

So, treat an unexpected backend CLOSED state the same as CLOSING.
