drm/nouveau/pmu: don't print reply values if exec is false
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")
