isdn: mISDN: netjet: fix wrong check of device registration
The class is set in mISDN_register_device(), but if device_add() returns
error, it will lead to delete a device without added, fix this by using
device_is_registered() to check if the device is registered.
Fixes: a900845e5661 ("mISDN: Add support for Traverse Technologies NETJet PCI cards")
