null-sink: Request no more than the configured latency from sink-input

In the case, where the latency is larger than the maximum block size,
module-null-sink will request multiples of the maximum block size from
the sink input instead of limiting the requested amount of data to the
the configured latency.

This patch fixes the problem.
