sched: Fix !CONFIG_SCHED_NUMA account_numa_enqueue() variant

This build warning:

  kernel/sched/fair.c:1015:1: warning: no return statement in function returning non-void

Triggers because the dummy account_numa_enqueue() should return the
rq's task list.

It's not possible to trigger this bug runtime, nevertheless fix the
warning.
