gpu: nvgpu: Wait for ECC scrubbing on all TPCs

We send a broadcast request to invoke scrubbing on all TPCs, but we
check only TPC0 for scrubbing to finish. This likely produces correct
results, because each TPC should take exactly the same number of cycles
for scrubbing, but it's not certain.

Change the polling loop to check all TPCs to make sure there are no
timing glitches.
