[PATCH v3 net-next 1/6] flow_dissector: constify bpf_flow_dissector's data pointers

[Alexander Lobakin <alobakin@xxxxx>]

BPF Flow dissection programs are read-only and don't touch input
buffers.
Mark 'data' and 'data_end' in struct bpf_flow_dissector as const
in preparation for global input constifying.
