[libvirt] [PATCH] qemu: driver: Unset log file watcher after restoring a VM save file

qemuProcessStart does not unset the infrastructure that retrieves errors from the qemu log file in case of migration. As this wasn't handled properly in qemuDomainSaveImageStartVM we kept the logging context/fd open for the lifetime of the VM rather than closing it after it's not needed.
