P2P: Fix wpas_remove_persistent_peer() to use P2P mgmt interface

The function used wpa_s->parent->conf to iterate the P2P networks and
update the configuration file. However, wpa_s->parent is not
necessarily the interface used to manage the P2P Device operations.

Fix this by accessing the configuration file of the interface
initialized to manage the P2P Device operations.
