Jouni Malinen c043b1e000 DPP: Remove unnecessary dpp_global_config parameters
These were not really used anymore since the AP/Relay case did not set
msg_ctx or process_conf_obj in the global DPP context. Get the
appropriate pointers more directly from the more specific data
structures instead and remove these global values.
