P2P NFC: Fix use of freed memory
The dev_found() callback from NFC connection handover message processing ended up using the p2p_dev_addr pointer that points to the parsed message. However, that parsed data was freed just before the call. Fix this by reordering the calls. Signed-off-by: Jouni Malinen <j@w1.fi>
