Trivial When creating a hostinterface via the API, the type field is not validated allowing for arbitrary type values to be send.
The API does not return an error but happily creates the interface.

This non-valid interface is not shown in the GUI, but some elements in the form to change. Also, the server/proxy/proxygroup selector breaks.
Saving the host from the frontend, removes the 'ghost interface' from the host.
Afterwards the form returns to normal.
