Currently all Checkmk filters are enabled by default although when unconfigured they remain passive. Most filters process data directly from the livestatus query but inventory filters perform a new query to obtain the SW/HW inventory of the host. Now inventory filters only query for data to filter for when they are actively configured, instead of gathering data at first and then deciding how to filter.

This fix increases the performance of the views, as fewer queries are done it thus speeds up the time to show a view.
