perf top/tui: Update nr_entries properly after a filter is applied
The hist_browser__reset() is only called right after a filter is
applied so it needs to udpate browser->nr_entries properly. 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.
