DPP: Indicate authentication success on ConfReqRX if needed

Browse source 
It is possible to receive the Configuration Request frame before having
seen TX status for the Authentication Confirm. In that sequence, the
DPP-AUTH-SUCCESS event would not be indicated before processing the
configuration step and that could confuse upper layers that follow the
details of the DPP exchange. As a workaround, indicate DPP-AUTH-SUCCESS
when receiving the Configuration Request since the Enrollee/Responser
has clearly receive the Authentication Confirm even if the TX status for
it has not been received.
