P2P: Deauth p2p client just after dbus notify

Currently to signal PropertiesChanged upon group client
removal (group property), wpa_supplicant dbus uses wpa_s
members like go_dev_addr and current_ssid, for instance.
Thus, deferring p2p client deauth to after dbus notify,
but keeping the same order as before, solves the issue,
as wpa_s is not yet completely deinitialized.
