sched/balancing: Rename run_rebalance_domains() => sched_balance_softirq()
run_rebalance_domains() is a misnomer, as it doesn't only
run rebalance_domains(), but since the introduction of the
NOHZ code it also runs nohz_idle_balance().
Rename it to sched_balance_softirq(), reflecting its more
generic purpose and that it's a softirq handler.
