Add virtio disk identification support
This patch adds the final missing bits for support of
passing a serial/id string to a virtio-blk guest driver.
So in order to SRU you will need to SRU linux (kernel) virtio_blk.c
changes, udev changes and qemu changes.
This has not been fixed in 10.10 or 11.04 either (despite my prior
claims.)
