perf test: Make the rdpmc test honour 'verbose' mode
It was unconditionally printing debug stuff when in non -v mode we
should just print the name and result of the test.
Now:
[root@sandy ~]# perf test rdpmc
6: x86 rdpmc test: Ok
[root@sandy ~]# perf test -v rdpmc
6: x86 rdpmc test:
--- start ---
0: 6030
1: 60030
2: 600050
3: 6000056
4: 60000070
5: 600000266
---- end ----
x86 rdpmc test: Ok
