[libvirt PATCH 17/30] qemu_snapshot: move snapshot metadata reparent code

[Pavel Hrdina]

Previously the reparent happened before the actual snapshot deletion.
This change moves the code closer to the rest of the code handling
snapshot metadata when deletion happens.

Following patch will extract it into separate function
