[libvirt PATCH 2/2] qemu_snapshot: create: don't require disk-only flag for offline external snapshot

Historically creating offline external snapshot required disk-only flag as well. Now when user requests new snapshot for offline VM and at least one disk is specified to use external snapshot we will no longer require disk-only flag as all other not specified disk will use external snapshots as well.
