DPP: Fix confusing debug entry from Configurator

DPP: Fix confusing debug entry from Configurator

The logic for displaying the message about no configuration being
available for the Enrollee was reversed when support for multiple Config
Objects was added. This was supposed to be shown only if the first
Config Object fails (i.e., when no configuration is available); not when
second attempt fails (since the first one had already been successful in
that case).
