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@intel.com> Fixes: d66f2b91f95b ("bpf: don't rely on the verifier lock for metadata_dst allocation") Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.
