P2P: Fix infinite loop on interface selection for Action frame TX

Browse source 
When the first wpa_supplicant interface is not the correct one for
transmitting an Action frame (e.g., P2P Presence Request frame
uses a group interface), the code got stuck in an infinite busy
loop. Fix the iteration to go through the interfaces properly.
