bpf: Reuse log from btf_prase_vmlinux() in btf_struct_ops_init()
Instead of using a locally defined "struct bpf_verifier_log log = {}",
btf_struct_ops_init() should reuse the "log" from its calling
function "btf_parse_vmlinux()". It should also resolve the
frame-size too large compiler warning in some ARCH.
