interconnect: qcom: osm-l3: Simplify osm_l3_set()

The aggregation over votes for all nodes in the provider will always
only find the bandwidth votes for the destination side of the path.
Further more, the average kBps value will always be 0.

Simplify the logic by directly looking at the destination node's peak
bandwidth request.
