[libvirt PATCH] qemu_snapshot: fix memory leak when reverting external snapshot
The code cleaning up virStorageSource doesn't free data allocated by
virStorageSourceInit() so we need to call virStorageSourceDeinit()
explicitly.
Fixes: 8e664737813378d2a1bdeacc2ca8e942327e2cab
Resolves: https://issues.redhat.com/browse/RHEL-33044
