HID: wacom: fix when get product name maybe null pointer
Due to incorrect dev->product reporting by certain devices, null
pointer dereferences occur when dev->product is empty, leading to
potential system crashes.
This issue was found on EXCELSIOR DL37-D05 device with
Loongson-LS3A6000-7A2000-DL37 motherboard.
