Bluetooth: Mesh: cfg_srv: Ignore Prohibited element addresses

The Configuration Model specification states that all non-unicast
addresses given as the address of an element are Prohibited. The
correct action for Prohibited parameter values is to ignore the
message. As of writing this patch the PTS does not enforce this, but
it might in the future (as it does for many other Prohibited values).
