The if_ plugins try to get the speed information from iwlist and fail. munin-node detect the failure and don't make if_* discoverable.

Please note that the traffic is shown in bits per second, not bytes. IMPORTANT: On 32 bit systems the data source for this plugin uses 32bit counters, which makes the plugin unreliable and unsuitable for most 100Mb (or faster) interfaces, where traffic is expected to exceed 50Mbps over a 5 minute period. This means that this plugin is unsuitable for most 32 bit production environments. To avoid this problem, use the ip_ plugin instead.

Think I'm having the same issue here as if_ graphs are also broken and getting the same error. I have commented out the munin-1.4.6-if_-hardened-v2.patch in local overlay and my graphs are back working again.

Can you please verify with 2.0.2-r1? Upstream merged and fixed that patch so it should work fine. Otherwise I need to find a way to actually understand what's going on as it doesn't fail here.
Fixed in net-analyzer/munin-2.0.2-r1.
