perf report: Make -D print sampled CPU

It is useful to know on which CPU a sample was captured on.
The information is captured with perf record -R but it was
not printed out by perf report -D. This patch adds this.

When -R is not used, cpu is set to -1to indicate that
the CPU is unknown (it is not captured).
