Subject: perf top: Fix refreshing hierarchy entries on TUI

From: Namhyung Kim <[email protected]>

commit c611152373e84a7677cd7d496e849de4debdab66 upstream.

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.
