CA-105159: Wait for ack of shutdown request for HVM guests with PV drivers

The code paths only handled fully-PV guests and HVM guests without PV drivers.
In the case of PV drivers we did not wait for the shutdown request to be
acknowledged. This did not enable early exit if the request was not
acknowledged.
