Jiri Olsa ab573844e3 perf: Fix hw breakpoints overflow period sampling 
The hw breakpoint pmu 'add' function is missing the
period_left update needed for SW events.

The perf HW breakpoint events use the SW events framework
to process the overflow, so it needs to be properly initialized
in the PMU 'add' method.
