perf top: Get rid of *_threaded() functions
Those _threaded() functions are needed to make hist tree handling
thread-safe, but AFAICS the only thing it does is forcing it to use
the intermediate 'collapsed' tree.
This can be acheived by setting sort__need_collapse to 1 in cmd_top() so
no need to keep those _threaded() variants.
