trafgen: Alloc cpus according to specified number of packets
Trafgen uses all the online CPUs even if the number of packets specified
by -n is less than the number 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 taking min(#CPUs, #packets) as the number of CPUs if a number
of packets is specified by -n.
