xenbus: move xenbus_dev_shutdown() into frontend code...
...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.
