selftests/intel_pstate: Fix warning on loop index overflow

The build was showing the warning:
 aperf.c:60:27: warning: iteration 2147483647 invokes undefined behavior
 [-Waggressive-loop-optimizations]
  for (i=0; i<0x8fffffff; i++) {

This change sets i, cpu and fd to unsigned int as they should not need
to be signed.
