perf: Fix multi-event parsing bug

This patch fixes an issue with event parsing.
The following commit appears to have broken the
ability to specify a comma separated list of events:

       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
