- 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().
