bpf: refactor bpf_helper_changes_pkt_data to use helper number
[ Upstream commit b238e187b4a2d3b54d80aec05a9cab6466b79dde ]
Use BPF helper number instead of function pointer in
bpf_helper_changes_pkt_data(). This would simplify usage of this
function in verifier.c:check_cfg() (in a follow-up patch),
where only helper number is easily available and there is no real need
to lookup helper proto.
