perf top: Fix refreshing hierarchy entries on TUI
Markus reported that 'perf top --hierarchy' cannot scroll down after
refresh. This was because the number of entries are not updated when
hierarchy is enabled.
Unlike normal report view, hierarchy mode needs to keep its own entry
count since it can have non-leaf entries which can expand/collapse.
