Reason for revert: the `fetchData` arg is used in cluster branch.

app/vmselect/netstorage: increase concurrency when processing small number of time series with big number of data points per each time series
...
Previously VictoriaMetrics was processing up to 32 time series in a single goroutine.
This could be slow if each time series contains big number of data points (10M+ or more), since only a single CPU core could be loaded with work,
while other CPU cores were idle. Fix this by launching GOMAXPROCS workers for time series processing.
This should help with https://github.com/VictoriaMetrics/VictoriaMetrics/issues/572
