Subject: pid_ns: de_thread: kill the now unneeded ->child_reaper change

de_thread() checks if the old leader was the ->child_reaper, this is not
possible any longer.  With the previous patch ->group_leader itself will
change ->child_reaper on exit.

Henceforth find_new_reaper() is the only function (apart from
initialization) which plays with ->child_reaper.
