DPP: Move manual mode auth resp processing to a helper function

This functionality needs to be used from multiple locations to fix
manual mode processing of Authentication Response with mutual
authentication, so move the functionality into a helper function. This
commit does not change behavior, i.e., it is only creating a helper
function from the existing implementation.
