DPP2: Fix Presence Announcement processing in Controller

Browse source 
Use the new struct dpp_authentication instance when setting Configurator
parameters for authentication exchange triggered by Presence
Announcement. conn->auth is NULL here and would cause dereferencing of a
NULL pointer if dpp_configurator_params is set.
