Keep stored row-averaged caches eligible on the fallback compute path

Browse Source 
ComputeWorker dropped row_avg_n, so a stored row-averaged cache was
ineligible whenever the fallback compute served the image instead of the
DC precompute path. Thread the viewer's precomputed_row_avg_n through
ComputeWorker and the batch export worker's compute_rf_image call.
