sched/fair: Remove cfs_rq::nr_spread_over and cfs_rq::exec_clock
nr_spread_over tracks the number of instances where the difference between a scheduling entity's virtual runtime and the minimum virtual runtime in the runqueue exceeds three times the scheduler latency, indicating significant disparity in task scheduling. Commit that removed its usage: 5e963f2bd: sched/fair: Commit to EEVDF cfs_rq->exec_clock was used to account for time spent executing tasks. Commit that removed its usage: 5d69eca542ee1 sched: Unify runtime accounting across classes cfs_rq::nr_spread_over and cfs_rq::exec_clock are not used anymore in eevdf. Remove them from struct cfs_rq.
