HID: Fix uninitialized variable "size" in hid-wiimote-debug
This variable is initialized conditionally, based on whether a wiimote
call succeeds. However, the logic is not obvious to the compiler so it
throws a warning. Eliminate the warning by initializing "size" to 0.
The warning is:
files/drivers/hid/hid-wiimote-debug.c:69:18: warning: 'size' may be used
uninitialized in this function [-Wmaybe-uninitialized]
