[PATCH 2/4] P2P: Fix wpas_p2p_set_own_freq_preference() to access the P2P mgmt interface

[Ilan Peer]

wpas_p2p_set_own_freq_preference() accesses wpa_s->parent->conf
to test if p2p_ignore_shared_freq is set, but 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.
