fork: remove use of percpu_counter_sum_all

Browse source

This effectively reverts the change made in commit f689054aac
("percpu_counter: add percpu_counter_sum_all interface") as the
race condition percpu_counter_sum_all() was invented to avoid is
now handled directly in percpu_counter_sum() and nobody needs to
care about summing racing with cpu unplug anymore.
