guard the nPho histograms from double counting, should fix HI issues

In HI reco DQM, photons are being double-counted because in HI RECO we do not pre-select at the RECO level for isolated photons. Since most HI photons are not isolated according to the default cuts they have type==0 and get double-counted. 
why not just remove all of the added lines and replace [0] by [type] in the two lines above?
