P2P: Cancel previous operation before starting new p2p_listen

Browse source 
Some drivers do not handle concurrent remain-on-channel operation
requests, so run p2p_stop_find() prior to starting p2p_listen. This
addresses some issues with P2P_LISTEN command being issues again
while already in Listen state.
