Daniel Borkmann 333a31c89a bpf: move {prev_,}insn_idx into verifier env
[ commit c08435ec7f upstream ]

Move prev_insn_idx and insn_idx from the do_check() function into
the verifier environment, so they can be read inside the various
helper functions for handling the instructions. It's easier to put
this into the environment rather than changing all call-sites only
to pass it along. insn_idx is useful in particular since this later
on allows to hold state in env->insn_aux_data[env->insn_idx].
