[Qemu-block] [PATCH RFC 0/1] vmstate: fix the failed iotests case 68 and 91

[QingFeng Hao]

Hi All,
I am not sure if the fix is correct because I am not very clear about the
logic in vmstate.c. From my test, once size=0, the iotests case 68 failed
due to the assert. So just send this draft patch for your comments!
The patch is based on commit 17783ac828a "Merge remote-tracking branch
'remotes/dgibson/tags/ppc-for-2.9-20170303' into staging".
Thanks!
