[pbs-devel] [PATCH proxmox-backup] api: tape: don't allow overwriting of ids in changer/drive config

[Dominik Csapak <d.csapak@proxmox.com>]

by checking the whole section config for an existing id, not only the
ones of the given type.

This prevents creation of a drive config with the same name as an
existing changer and vice versa.
