usb: sisusb_con: Use array_size() helper in memcpy()
Use array_size() helper instead of the open-coded version in memcpy(). These sorts of multiplication factors need to be wrapped in array_size(). This issue was found with the help of Coccinelle and, audited and fixed manually. Addresses-KSPP-ID: https://github.com/KSPP/linux/issues/83 Signed-off-by: Gustavo A. R.
