Subject: [PATCH v2] wusb: use correct format characters

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')
  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.
