Yes, that gets a bit tricky here... Disk serial number is specified in
QEMU command line parameters, so it needs to be passed to vhost_blk
when qemu attaches the disk backend. That can be done (now? in a
following incremental patch?).
Also other vhost work does the same with GET_ID, if that's matter.

I'll fix the rest, thanks for review!
