app/vmselect/promql: remove duplicated logic of filling NaN values for histograms

Browse source 
Removed logic was used to fill nan values with lower buckets values: [1 2 3 nan nan nan] => [1 2 3 3 3 3].
Since buckets are now fixed from lower ones to upper this happens in the main loop, so there is no need in a second one.
