  sched_ext: idle: Refresh idle masks during idle-to-idle transitions (2025-01-10 12:40:42 -1000)

----------------------------------------------------------------
sched_ext: Fixes for v6.13-rc6

- Fix corner case bug where ops.dispatch() couldn't extend the execution of
  the current task if SCX_OPS_ENQ_LAST is set.

- Fix ops.cpu_release() not being called when a SCX task is preempted by a
  higher priority sched class task.

- Fix buitin idle mask being incorrectly left as busy after an idle CPU is
  picked and kicked.

- scx_ops_bypass() was unnecessarily using rq_lock() which comes with rq
  pinning related sanity checks which could trigger spuriously. Switch to
  raw_spin_rq_lock().
