power_supply_get_property() should ideally return -EAGAIN if it is called while the power_supply is being registered. There was no way previously to determine if use_cnt == 0 meant that the power_supply wasn't fully registered yet, or if it had already been unregistered. Add a new boolean to the power_supply struct to simply show if registration is completed. Lastly, modify the check in power_supply_show_property() to also ignore -EAGAIN when so it doesn't complain about not returning the property.
