DPP2: Clear requirement for QR Code mutual authentication for chirping
The chirping cases are not really targeting interactive operations, so
clear the requirement for mutual authentication when DPP_CHIRP command
is used. This avoids testing isues where an earlier DPP_LISTEN command
has used qr=mutual parameter and that seting not getting cleared before
the next DPP_CHIRP command is used.
This fixes a test case failure in the following test sequence:
dpp_auth_resp_status_failure dpp_controller_relay_chirp
