bpf: adjust insn_aux_data when patching insns

Browse source

From: Alexei Starovoitov <ast@fb.com>

[ Upstream commit 8041902dae ]

convert_ctx_accesses() replaces single bpf instruction with a set of
instructions. Adjust corresponding insn_aux_data while patching.
It's needed to make sure subsequent 'for(all insn)' loops
have matching insn and insn_aux_data.
