serial: jsm: Drop unused driver_data assigment and redundant zeros

The driver doesn't use the driver_data field, so drop the assigment
together with the then redundant zero assigment for .class and
.class_mask. Also drop the zero in the list terminator.

While at it also use PCI_VDEVICE() to allow dropping "PCI_VENDOR_ID_".
