sched: Optimize the !power_savings_balance during fbg()
Impact: cleanup, micro-optimization
We don't need to perform power_savings balance if either the
cpu is NOT_IDLE or if the sched_domain doesn't contain the
SD_POWERSAVINGS_BALANCE flag set.
Currently, we check for these conditions multiple number of
times, even though these variables don't change over the scope
of find_busiest_group().
Check once, and store the value in the already exiting
"power_savings_balance" variable.
