exit: ptrace: shift "reap dead" code from exit_ptrace() to forget_original_parent()
Now that forget_original_parent() uses ->ptrace_entry for EXIT_DEAD tasks,
we can simply pass "dead_children" list to exit_ptrace() and remove
another release_task() loop. Plus this way we do not need to drop and
reacquire tasklist_lock.
Also shift the list_empty(ptraced) check, if we want this optimization it
makes sense to eliminate the function call altogether.
