perf stat: Fix verbose for perf stat
Error message should use stderr for verbose (-v), otherwise
message will be lost for:
$ ./perf stat -v <cmd> > /dev/null
For example on AMD bus-cycles event is not available so now
it looks like:
$ ./perf stat -v -e bus-cycles ls > /dev/null
Error: counter 0, sys_perf_counter_open() syscall returned with -1 (Invalid argument)
Performance counter stats for 'ls':
<not counted> bus-cycles
