sched: Replace first_cpu() with cpumask_first() in ILB nomination code

For !(CONFIG_SCHED_MC || CONFIG_SCHED_SMT), find_new_ilb() nominates the
Idle load balancer as the first cpu from the nohz.cpu_mask.
This code uses the older API first_cpu(). Replace it with cpumask_first(),
which is the correct API here.
[ Impact: cleanup, address build warning ]
