can: peak_usb: pcan_usb_{,pro}_get_device_id(): remove unneeded check for device_id
The callback struct peak_usb_adapter::dev_get_device_id, which is implemented by the functions pcan_usb_{,pro}_get_device_id() is only ever called with a valid device_id pointer. This patch removes the unneeded check if the device_id pointer is valid.
