usb: cdns3: Fix Wunused-but-set-variable warning
drivers/usb/cdns3/ep0.c: In function cdns3_ep0_feature_handle_device:
drivers/usb/cdns3/ep0.c:290:6: warning: variable wIndex set but not used [-Wunused-but-set-variable]
drivers/usb/cdns3/ep0.c:289:6: warning: variable wValue set but not used [-Wunused-but-set-variable]
wIndex is never used, so remove it.
wValue should be use in the switch statement.
