The hists->nr_entries is counted in multiple places so that they can confuse readers of the code. This is a preparation of later change and do not intend any functional difference. Note that report__collapse_hists() now changed to return nothing since its return value (nr_samples) is only for checking if there's any data in the input file and this can be acheived by checking ->nr_entries.
