Andrii Nakryiko 1a1ad782dc bpf: tidy up exception callback management a bit ... Use the fact that we are passing subprog index around and have a corresponding struct bpf_subprog_info in bpf_verifier_env for each subprogram. We don't need to separately pass around a flag whether subprog is exception callback or not, each relevant verifier function can determine this using provided subprog index if we maintain bpf_subprog_info properly. Also move out exception callback-specific logic from btf_prepare_func_args(), keeping it generic. We can enforce all these restriction right before exception callback verification pass. We add out parameter, arg_cnt, for now, but this will be unnecessary with subsequent refactoring and will be removed.
