kernel test robot reported: WARNING: CPU: 0 PID: 1244 at net/netfilter/core.c:218 __nf_hook_entries_try_shrink+0x49/0xcd [..] After allowing batching in nf_unregister_net_hooks its possible that an earlier call to __nf_hook_entries_try_shrink already compacted the list. If this happens we don't need to do anything.
