i2c: cp2615: fix serial string NULL-deref at probe
The cp2615 driver uses the USB device serial string as the i2c adapter
name but does not make sure that the string exists.
Verify that the device has a serial number before accessing it to avoid
triggering a NULL-pointer dereference (e.g. with malicious devices).
