[PATCH 5/7] sched: pass struct rq to rebalance_domains function

[Daniel Lezcano <daniel.lezcano@linaro.org>]

The cpu information is stored in the struct rq and the caller of the
rebalance_domains function pass the cpu to retrieve the struct rq but
it already has the struct rq info. Replace the cpu parameter with the
struct rq.
