In case of BPF_CORE_TYPE_ID_LOCAL we fill out target result explicitly. But targ_res itself isn't initialized in such a case, and subsequent call to bpf_core_patch_insn() might read uninitialized field (like fail_memsz_adjust in this case). So ensure that targ_res is zero-initialized for BPF_CORE_TYPE_ID_LOCAL case. This was reported by Coverity static analyzer.
