Previously, RSMI assumed that the event counter values returned from perf were only new events. But in fact, when we read the counter values, they are running totals. To account for this, we now record the value we read and take the difference between the current value and the previously recorded value. Change-Id: I1e04b514e89c7c4d4719889f2dae3a1283864e7f
