[Intel-gfx] [PATCH i-g-t] intel_gpu_top: Fix frequency and rc6 counters

[Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com>]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Need to reset aggregated counters before adding to them otherwise numbers
will grow endlessly.

Fixes: 3dadeff69d4a ("intel_gpu_top: Switch pmu_counter to use aggregated values")
