    Fix renew_until check for auto-renewal
    
    This was completely wrong, but only caused a severe problem on 64 bit
    builds. On 32 bit builds the result was effectively always 'success',
    so it would always attempt to renew even if there was not sufficient time
    left in the renewable lifetime. This did not have much observable
    adverse effect. But on 64 bit builds it always failed and so never
    attempted renewal.
