bpf: remove obsolete prog->aux sanitation in bpf_insn_prepare_dump
This logic is not needed anymore since we got rid of the verifier rewrite that was using prog->aux address in f6069b9aa993 ("bpf: fix redirect to map under tail calls"). Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
