profiles/battery: handle reversed ordering of CCC and value Order of batt_io_value_cb() and batt_io_ccc_written_cb() may be reverse. This causes device to appear with 0% or missing battery percentage, because batt->percentage is set on the ignored update so the initial update is lost. Fix by saving new initial value, if battery is not registered. Also downgrade warning to debug message. Also check data length before parsing it.
