Curl_timediff rounds down to the millisecond, so curl_multi_perform can be called too early, then we get a timeout of 0 and call it again. The code already handled the case of timeouts which expired less than 1ms in the future. By rounding up, we make sure we will never ask the platform to wake up too early. Closes #11938
