589bf1f7a9 DPP2: Fix ppkey parsing
DPP_CONFIGURATOR_ADD processing of the new ppkey parameter had a
copy-paste error in determining the correct length of this parameter.
Fix that by referencing the correct pointer.

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.

574a8fa6c8 DPP: Do not interpret unknown channel as missing channel list for NFC
While the listed unknown operating class/channel number pairs need to be
ignored, that should be done in a manner than prevents the parsed
bootstrapping info from being used as if it had no channel list (i.e.,
allowing any channel) if there are no known operating class/channel
number pairs.
