Subject: libbpf: Avoid false unuinitialized variable warning in
 bpf_core_apply_relo
Patch-mainline: v5.10-rc1
Git-commit: 3418c56de81fd73f2265c8915f4b910bcc141cb7
References: bsc#1177028

Some versions of GCC report uninitialized targ_spec usage. GCC is wrong, but
let's avoid unnecessary warnings.

Fixes: ddc7c3042614 ("libbpf: implement BPF CO-RE offset relocation algorithm")
