From: Alexei Starovoitov <ast@xxxxxxxxxx>
When CONFIG_DEBUG_INFO_BTF_MODULES is not set
the following warning can be seen:
kernel/bpf/btf.c:6588:13: warning: 'purge_cand_cache' defined but not used [-Wunused-function]
Fix it.
Fixes: 1e89106da253 ("bpf: Add bpf_core_add_cands() and wire it into bpf_core_apply_relo_insn().")
