virtio: Allow .get_vhost() without vhost_started
Historically, .get_vhost() was probably only called when vdev->vhost_started is true. However, we now decidedly want to call it also when vhost_started is false, specifically so we can issue a reset to the vhost back-end while device operation is stopped. Some .get_vhost() implementations dereference some pointers (or return offsets from them) that are probably guaranteed to be non-NULL when vhost_started is true, but not necessarily otherwise. This patch makes all such implementations check all such pointers, returning NULL if any is NULL.
