commit 4ae834f767 (sched/numa: Implement NUMA home-node selection code)
caused the following warning on a !CONFIG_SMP system:
kernel/sched/fair.c:1013:13: warning: 'account_offnode_enqueue' defined but not
used [-Wunused-function]
Since account_offnode_enqueue() is only used in a path that requires CONFIG_SMP
to be enabled, make its definition dependent on CONFIG_SMP.
