[libvirt PATCH v2 29/81] qemu: Preserve error in qemuMigrationDstFinish

[Jiri Denemark]

We want to prevent our error path that can potentially kill the domain
on the destination host from overwriting an error reported earlier, but
we were only doing so in one specific path when starting vCPUs fails.
Let's do it in all paths.
