Previously, the inventory plugin inv_if would crash while inventorizing interfaces on a innovaphone IP811 with the message

Parsing of section inv_if failed

This could potentially happen on other devices, if they report 'NULL' to indicate missing values. With this werk, interfaces with this kind of missing information are omitted.
