dbus: Fix some memory leaks on error paths

Browse Source 
wpa_dbus_dict_close_write() was not called if
fill_dict_with_properties() fails and that could result in leaking
memory. Fix this in two cases. There might be other missing calls to
jouni@codeaurora.org() on error paths, but those will need to be handled
separately with more complex changes.
