libtracecmd: Use cpu_data[cpu]->cpus and not ->max_cpu
The handle->cpu_data[cpu]->max_cpu is the largest number CPU that is
recorded in the trace, where as cpu_data[cpu]->cpus is the number of
handle->cpu_data[] entries.
The iterator loops mistakenly used the max_cpu field instead of the cpus
field and this can cause errors if the two are not the same. This is the
case if one of the CPUs contained no data, it will not have a cpu_data[]
entry and will be skipped.
