When compiling with -Wformat, clang warns: ./include/linux/usb/wusb.h:245:5: warning: format specifies type 'unsigned short' but the argument has type 'u8' (aka 'unsigned char') [-Wformat] ckhdid->data[0], ckhdid->data[1], ^~~~~~~~~~~~~~~
ckhdid->data is unconditionally defined as `u8 data[16]`, so this patch updates the format characters to the correct one for unsigned char types.
