Subject: net: dst: move cpu inside ifdef to avoid compilation warning
Patch-mainline: v4.15-rc1
Git-commit: 833e0e2f24fd0525090878f71e129a8a4cb8bf78
References: bsc#1083647
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")
