virtio-blk-pci, virtio-blk-s390, and virtio-blk-ccw all duplicate the qdev properties of their VirtIOBlock child. This approach does not work well with string or pointer properties since we must be careful about leaking or double-freeing them. Use the QOM alias property to forward property accesses to the VirtIOBlock child. This way no duplication is necessary. Remember to stop calling virtio_blk_set_conf() so that we don't clobber the values already set on the VirtIOBlock instance.
