[libvirt] [PATCH] qemuDomainSnapshotCreateActiveExternal: Remove memory snapshot on failure less frequently


When creating a memory snapshot the domain is suspended and qemu
is told to dump memory into the desired file. After that we set a
flag so that the file is not left behind if a failure occurs at
some later point (e.g. when creating disk snapshot fails).
However, the way we currently handle the memory snapshot file is
way too aggressive. For instance, if resuming domain vCPUs fails
after all snapshots were done successfully, we still remove the
memory snapshot (even though we leave disk snapshot be).
