perf hists: Add missing update on filtered stats in hists__decay_entries()
perf hists: Add missing update on filtered stats in hists__decay_entries()

When a filter is used for perf top, its hists->nr_non_filtered_entries
was not updated after it removed an entry in hists__decay_entries().
Also hists->stats.total_non_filtered_period was missed too.
