virtio_blk: Revert serial number support
This reverts "Add serial number support for virtio_blk, V4a". Turns out that virtio_pci, lguest and s/390 all have an 8 bit limit on virtio config space, so noone could ever use this. This is coming back later in a cleaner form. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: john cooper <john.cooper@redhat.com> Cc: Jens Axboe <jens.axboe@oracle.com>
