sched_ext: Skip per-CPU tasks in scx_bpf_reenqueue_local()
scx_bpf_reenqueue_local() can be invoked from ops.cpu_release() to give
tasks that are queued to the local DSQ a chance to migrate to other
CPUs, when a CPU is taken by a higher scheduling class.
However, there is no point re-enqueuing tasks that can only run on that
particular CPU, as they would simply be re-added to the same local DSQ
without any benefit.
Therefore, skip per-CPU tasks in scx_bpf_reenqueue_local().
