bpf: fix visit_insn()'s detection of BPF_FUNC_timer_set_callback helper
It's not correct to assume that any BPF_CALL instruction is a helper
call. Fix visit_insn()'s detection of bpf_timer_set_callback() helper by
also checking insn->code == 0. For kfuncs insn->code would be set to
BPF_PSEUDO_KFUNC_CALL, and for subprog calls it will be BPF_PSEUDO_CALL.
