This is done in order to make sure the htc ctrl service is setup properly before hif_start is called. The reason for this is that we want the HTC ctrl service callback to be initialized before the target sends the HTC ready message. The ready message will always be transmitted on endpoint 0 (which is always assigned to the HTC control service) so it makes more sense if HTC control has been connected before the ready message is received. Since the service to pipe mapping is done as a part of the service connect, the get_default_pipe call is redundant and was removed.
