Inconsistent list of inactive ports with "port list inactive" command

[Marko Käning]

I noticed that the list of inactive ports printed by "port list inactive" doesn't seem to be consistent.

See below for exemplary output. Compare with this with the more sensible output of "port installed"!!!

It looks like there is an offset (or even a not properly set index) when accessing the list of inactive ports.

Also the revision is not displayed, which would make sense sometimes.
