Trafgen uses all the online cpus even if number of packets specified
by -n is less than numbers of selected cpus.
Such behaviour leads to issues:
- trafgen re-calculates number of packets per cpu which
leads to rounding it to 0 then no packets will be sent.
- trafgen might send more packets than specified by -n because
of using all the online cpus.
Fixed by calculation the minimum number of cpus for generation
number of packets specified by -n.
