perf hist: Initialize hierarchy tree explicitly
The hroot_in and hroot_out are roots of hierarchy trees of hist entries. But when a hist entry is initialized by copying existing template entry, it sometimes has non-empty tree and copies it incorrectly. This is a problem especially when an event group is used since it creates dummy entries from already-processed entries in other event members.
