Subject: [PATCH net-next] net: dst: move cpu inside ifdef to avoid compilation warning
If CONFIG_DST_CACHE is not selected cpu variable
will be unused and we will see a compilation warning.
Move it under the ifdef.
Reported-by: kbuild test robot <fengguang.wu@...el.com>
Fixes: d66f2b91f95b ("bpf: don't rely on the verifier lock for metadata_dst allocation")
