Subject: [PATCH BlueZ] mesh: Fix to duplicated model Ids saved to storage

BlueZ internally implements a SIG model for Config Server.

When generating node, if the Mesh Element in mesh application returns modelId 0
among its supported models, it should be skipped, otherwise it will be
duplicated and saved in the storage file.

This patch fixes correctly skipping Config Server model during node creation.
