Zqiang ab28a0673d sched_ext: Use IRQ_WORK_INIT_HARD() to initialize sch->disable_irq_work ...

For built with PREEMPT_RT kernels, the scx_disable_irq_workfn() is
called from per-cpu irq_work kthreads context, this means that
when call the scx_dump_state() in the scx_disable_irq_workfn() to
output current->comm/pid, it always output current irq_work kthread's
comm/pid. this commit therefore use the IRQ_WORK_INIT_HARD() to
initialize sch->disable_irq_work to make scx_disable_irq_workfn() is
called from hardirq context.

Fixes: f4a6c506d1 ("sched_ext: Always bounce scx_disable() through irq_work")
