USB: symbolserial: Use usb_get_serial_port_data
commit 951d3793bbfc0a441d791d820183aa3085c83ea9 upstream. The driver used usb_get_serial_data(port->serial) which compiled but resulted in a NULL pointer being returned (and subsequently used). I did not go deeper into this but I guess this is a regression.
