P2P: Fix wpas_p2p_set_own_freq_preference() to use P2P mgmt interface

wpas_p2p_set_own_freq_preference() accessed 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.
