Ignoring OOM is risky. If managed_save is NULL, we are out of memory,
and we should fail the command; that's the only time that
qemuDomainManagedSavePath returns NULL. We don't know if there was a
save file or not. And even if there was not a file, we'd probably run
out of memory again if we attempt normal setup.
