Subject: [PATCH tip/core/rcu 17/20] doc: Make listing in RCU perf/scale requirements use rcu_assign_pointer()

From: "Joel Fernandes (Google)" <joel@...lfernandes.org>

The code listing under this section has a quick quiz that says line
19 uses rcu_access_pointer, but the code listing itself instead uses
rcu_dereference().  This commit therefore makes the code listing match
the quick quiz.
