Hou Tao 2f553b032c selftsets/bpf: Retry map update for non-preallocated per-cpu map ... BPF CI failed due to map_percpu_stats_percpu_hash from time to time [1]. It seems that the failure reason is per-cpu bpf memory allocator may not be able to allocate per-cpu pointer successfully and it can not refill free llist timely, and bpf_map_update_elem() will return -ENOMEM. So mitigate the problem by retrying the update operation for non-preallocated per-cpu map.
