irq/work: Use llist_for_each_entry_safe
The llist_for_each_entry() loop in irq_work_run_list() is unsafe because
once the works PENDING bit is cleared it can be requeued on another CPU.
Use llist_for_each_entry_safe() instead.
Fixes: 16c0890dc66d ("irq/work: Don't reinvent the wheel but use existing llist API")
