wmbattery: upower - don't exit after suspend/hibernation wakup

Browse source 
Immediately after suspend/hibernation wakup cycle, up_client_get_devices()
can fail:

 libupower-glib-WARNING **: up_client_get_devices failed: Timeout was reached

Since we do not interpret the UPower signals, just don't exit wmbattery after
first up_client_get_devices() failure.
