virtio-blk: use aliases instead of duplicate qdev properties
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.
