device: fix build warning when CFG_TUSB_DEBUG >= 2 

The function is defined inside of a function body which generates a
warning.  Circuit Python treats these warnings as errors, and so
refuses to build with debugging enabled:

    ../../lib/tinyusb/src/device/usbd_control.c: In function 'usbd_control_xfer_cb':
    ../../lib/tinyusb/src/device/usbd_control.c:195:19: error: nested extern declaration of 'usbd_driver_print_control_complete_name' [-Werror=nested-externs]
      195 |       extern void usbd_driver_print_control_complete_name(bool (*control_complete) (uint8_t, tusb_control_request_t const *));
          |                   ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    cc1: all warnings being treated as errors
    make: *** [../../py/mkrules.mk:55:
    build-simmel/lib/tinyusb/src/device/usbd_control.o] Error 1

Move the declaration to the top of the function to silence this warning.
