We cannot use hists->nr_non_filtered_entreis directly since it's possible that such entries are also filtered out by minimum percentage limit. In addition when a filter is used for perf top, hist browser's nr_entries field was not updated after applying the filter. But it needs to be updated as new samples are coming.
