sched/balancing: Rename load_balance() => sched_balance_rq()
Standardize scheduler load-balancing function names on the
sched_balance_() prefix.
Also load_balance() has become somewhat of a misnomer: historically
it was the first and primary load-balancing function that was called,
but with the introduction of sched domains, it's become a lower
layer function that balances runqueues.
Rename it to sched_balance_rq() accordingly.
