P2P: Fix return value of p2p_reply_probe() and p2p_probe_req_rx()

Browse source 
Return P2P_PREQ_PROCESSED instead of P2P_PREQ_NOT_PROCESSED on
a successful Probe Request frame handling in p2p_reply_probe().

Verify a return value of p2p_reply_probe() in p2p_probe_req_rx()
and continue a pending invitation/connection flow only if the
Probe Request frame is from an expected P2P peer.
