Instead of doing so in the constructor, let's do immediately after the constructor, so we can safely pass a reference of a Device, so the SysFSDeviceComponent constructor can use that object to identify whether it's a block device or a character device. This allows to us to not hold a device in SysFSDeviceComponent with a RefPtr. Also, we also call the before_removing method in both SlavePTY::unref and File::unref, so because Device has that method being overrided, it can ensure the device is removed always cleanly.
