In wakeup_next_waiter(), we take the pi_lock, and then find out whether
we have another waiter to add to the pending owner.  We can reduce
contention on the pi_lock for the pending owner if we first obtain the
pointer to the next waiter outside of the pi_lock.

This patch adds a measureable increase in throughput.
