[libvirt] [PATCH] remote: check & report OOM in make_nonnull_XXX methods

The make_nonnull_XXX methods can all fail due to OOM but this was being silently ignored and thus also not checked by callers. Make the methods propagate errors and use ATTRIBUTE_RETURN_CHECK to force callers to deal with it. Signed-off-by: Daniel P.
