dbus: Reorder deauthentication and cleanup calls when removing a network...

....

Valgrind indicates reference to already freed memory if function
wpa_config_remove_network() is called prior to calling
wpa_supplicant_deauthenticate(), and this can lead to a crash.
Inverting the call order fixes the problem.
