perf stat: Fail more clearly when an invalid modifier is specified
This patch fixes this while preserving the desired effect:
$ perf stat -e instructions:u,instructions:k ls /dev/null /dev/null
Performance counter stats for 'ls /dev/null':
365956 instructions:u # 0.00 insns per cycle
731806 instructions:k # 0.00 insns per cycle
0.001108862 seconds time elapsed
$ perf stat -e task-clock-msecs true
invalid event modifier: '-msecs'
Run 'perf list' for a list of valid events and modifiers
