perf hists browser: Update the browser.nr_entries after the timer

Browse source 
Previously the hist_browser dealt with a static tree of entries, now it
needs to update the nr_entries in the browser after the timer runs.

A better solution will come when moving using another thread for the
collapse_resort, etc, but for now this is ok.
