Subject: [PATCH] flush cache in bp_index

netdisco/netdisco#496 has more background on the issue.

somewhere incorrect data is returned for bp_index mappings when running macsuck, but i cannot reproduce this when using snmp::info directly.

forcing i_index to reload works around the issue, performance impact is minimal.
