Martin KaFai Lau fdbaa0beb7 bpf: Ensure line_info.insn_off cannot point to insn with zero code
This patch rejects a line_info if the bpf insn code referred by
line_info.insn_off is 0. F.e. a broken userspace tool might generate
a line_info.insn_off that points to the second 8 bytes of a BPF_LD_IMM64.
