  bpf: Convert ringbuf map to rqspinlock (2025-04-11 10:28:26 -0700)

----------------------------------------------------------------
- Followup fixes for resilient spinlock (Kumar Kartikeya Dwivedi)
  . Make res_spin_lock test less verbose, since it was spamming
    BPF CI on failure, and make the check for AA deadlock stronger
  . Fix rebasing mistake and use architecture provided
    res_smp_cond_load_acquire
  . Convert BPF maps (queue_stack and ringbuf) to resilient
    spinlock to address long standing syzbot reports

- Make sure that classic BPF load instruction from SKF_[NET|LL]_OFF
  offsets works when skb is fragmeneted (Willem de Bruijn)
