[libvirt] [PATCH 3/8] qemu: snapshot: Unify conditions checking whether snapshot needs to be taken
In the cleanup path we already checked whether a snapshot needed to be
taken by looking into the collected data. Use the same approach when
creating the snapshot command data and when commiting the changes to the
domain definition.
