[Qemu-devel] [FIX V2] repair snapshots

[Benoît Canet]

This patch fix the snapshoting code.

When initially testing block filter snapshots patches and quorum I used a wrong
quorum command line which containned an extra top level "file."

As a result quorum was encapsulated in a top level bs.

This caused me to write and test against the wrong configuration and
break snapshot.

This patch implement Kevin sugestion for the fix.

I tested

snapshot of a Blockbackend: ex virtio0 ok
snapshot of a quorum file instantiated in the command line. ok
snapshot of a quorum file instantiated via blockdev_add by references ok
snapshot of a quorum file instianciated via blockdev without references ok

A comment update for quorum will be needed to avoid user to use the wrong
command line.
