From: Colin Ian King <colin.k...@canonical.com>

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)")
