upstream: Fix calculation of initial bandwidth limits. Account for
written bytes before the initial timer check so that the first buffer written
is accounted. Set the threshold after which the timer is checked such that
the limit starts being computed as soon as possible, ie after the second
buffer is written. This prevents an initial burst of traffic and provides a
more accurate bandwidth limit. bz#2927, ok djm.
