sched/fair: Revert max_newidle_lb_cost bump
Many people reported regressions on their database workloads due to:
155213a2aed4 ("sched/fair: Bump sd->max_newidle_lb_cost when newidle balance fails")
For instance Adam Li reported a 6% regression on SpecJBB.
Conversely this will regress schbench again; on my machine from 2.22
Mrps/s down to 2.04 Mrps/s.
