From: Michal Kazior <michal@xxxxxxxxx>
DPP configurator params can be configured per
interface. DPP listening can also be started and
stopped per interface.
However DPP rx processing was always doomed to
process incomming frames even on interfaces which
were not explicitly started to do DPP listen. This
happened because not only the initial value but
also because the dpp_allowed_roles could never be
reset to 0.
This would result in random failures in
configuring Enrollees when running multiple AP
interfaces if some of these APs happened to not
have DPP configurator params set.
