usb: gadget: g_dnl: hold maximum string descriptor
A USB String descriptor can be up to 255 characters long and it's not NULL terminated according to the USB spec. This means our MAX_STRING_SERIAL should be 256 (to cope with NULL terminator). Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
