D-Bus: Fix P2P peer joined/disconnected handlers
It is possible for the peer to be a non-P2P device and as such, for p2p_dev_addr to be NULL. This resulted in NULL pointer dereference if D-Bus interface was enabled for the interface when a legacy STA joined a group. Signed-off-by: Jouni Malinen <j@w1.fi>
