Fix a verification failure. filter_udphdr() calls bpf_xdp_pull_data(),
which will invalidate all pkt pointers. Therefore, all ctx->data loaded
before filter_udphdr() cannot be used. Reload it to prevent verification
errors.
The error may not appear on some compiler versions if they decide to
load ctx->data after filter_udphdr() when it is first used.
