[PATCH container 7/8] volume rescan: also consider volumes listed only with an approximate size

[Fiona Ebner <f.ebner@proxmox.com>]

While currently qcow2 volumes on LVM are the only ones for which an
approximate size might be returned instead of an exact size when
listing the volumes, there might be more storages doing this in the
future, so prepare for that.
