[dpdk-dev] [PATCH v1] examples/power: fix busyness number limed to 50%

Current implementation only outputs 3 numbers for busyness, 0, 50 and 100.
Fix this so that the 50% is replaced by a curve, more meaningful.
This can be replaced in each use case by a suitable calculation for
that use case.
Fixes: 609e79841fcf ("examples/l3fwd-power: add telemetry mode")
