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

[Tvrtko Ursulin]

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

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

Signed-off-by: Tvrtko Ursulin <tvrtko.ursu...@intel.com>
Fixes: 3dadeff69d4a ("intel_gpu_top: Switch pmu_counter to use aggregated 
values")
