Fix parsing of hids and ids

  If we get an id insted of a hid we failed beacuse
we passed the wrong variable.

I also added some more comments.

Fixes: #11453

Hi,

I think this patch confuses a few things that we should not confuse.

HID = Human IDs - readable by a human - that's it; and IDs which are readable by
a machine and easier to handle - therefore faster code

The function zone_config_id_is_valid should never take a HID. If it does its
name is wrong.

The internal functions should never handle HIDs.
