kernel: queue: k_queue_poll: Fix slist access race condition All sys_slist_*() functions aren't threadsafe and calls to them must be protected with irq_lock. This is usually done in a wider caller context, but k_queue_poll() is called with irq_lock already relinquished, and is thus subject to hard to detect and explain race conditions, as e.g. was tracked in #4022.
