[libvirt PATCH] qemu_snapshot: external: don't error out when updating metadata

Attaching disk into running VM the offilne definition may not be updated and we will end up with that disk existing only in live definition. Creating snapshot with this state saves both live and offline definition into snapshot metadata. When we are deleting an external snapshot we are updating these definitions in the snapshot metadata so we should just skip over non-existing disks instead of reporting error.
