[ Upstream commit b1d03fc36ec9834465a08c275c8d563e07f6f6bf ]
Currently the uninitialized values in the array reply are printed out when exec is false and nvkm_pmu_send has not updated the array. Avoid confusion by only dumping out these values if they have been actually updated.
Detected by CoverityScan, CID#1271291 ("Uninitialized scaler variable") Fixes: ebb58dc2ef8c ("drm/nouveau/pmu: rename from pwr (no binary change)")
