After qemu_iovec_destroy, the QEMUIOVector's size is zeroed and the zero size ultimately is used to compute virtqueue_push's len argument. Therefore, reads from virtio-blk devices did not migrate their results correctly. (Writes were okay). Save the size in virtio_blk_handle_request, and use it when the request is completed. Based on a patch by Wen Congyang.
