    ...and make it static
    
    xenbus_dev_shutdown() is seemingly intended to cause clean shutdown of PV
    frontends when a guest is rebooted. Indeed the function waits for a
    conpletion which is only set by a call to xenbus_frontend_closed().
    
    This patch removes the shutdown() method from backends and moves
    xenbus_dev_shutdown() from xenbus_probe.c into xenbus_probe_frontend.c,
    renaming it appropriately and making it static.
    
    NOTE: In the case where the backend is running in a driver domain, the
          toolstack should have already terminated any frontends that may be
          using it (since Xen does not support re-startable PV driver domains)
          so xenbus_dev_shutdown() should never be called.
