Eduard Zingerman 13f843c017 bpf: frame_insn_idx() utility function
A function to return IP for a given frame in a call stack of a state.
Will be used by a next patch.

The `state->insn_idx = env->insn_idx;` assignment in the do_check()
allows to use frame_insn_idx with env->cur_state.
At the moment bpf_verifier_state->insn_idx is set when new cached
state is added in is_state_visited() and accessed only in the contexts
when the state is already in the cache. Hence this assignment does not
change verifier behaviour.
