Suspend/Resume to/from disk currently fails. Let us wire up the necessary callbacks. This is mostly just forwarding the requests to the virtio drivers. The only thing that has to be done in virtio_ccw itself is to re-set the virtio revision.

Hi, here is an updated patch-set with changes as suggested by Michael Tsirkin. When an active virtio block device is hot-unplugged from a KVM guest, running affected guest user applications are not aware of any errors that occur due to the lost device. This patch-set adds code to avoid further request queueing when a lost block device is detected, resulting in appropriate error info. On System z
