perf: Mark software events as irqsafe
Noticed while using 'perf top' on a machine without a supported PMU on
2.6.33.7-rt29, when top falls back to using the "cpu-clock" software
event.
Reproduced on other machines where the problem was masked due to the
existence and use of hardware events, by explicitely asking for a
software event using:
perf top -e cpu-clock
