rcu: Update rcu_access_pointer() header for rcu_dereference_protected()

Browse source

The rcu_access_pointer() docbook header correctly notes that it may be
used during post-grace-period teardown.  However, it is usually better to
use rcu_dereference_protected() for this purpose.  This commit therefore
calls out this preferred usage.
