HID: nintendo: stop device IO before hid_hw_stop on probe failure
nintendo_hid_probe() calls hid_device_io_start() before joycon_init()
and joycon_leds_create(). If either fails, the error path jumps to
err_close which calls hid_hw_close()/hid_hw_stop() without first calling
hid_device_io_stop().
hid_hw_stop() does not stop device IO, so hid_input_report() may still
run and access driver data that is being torn down, resulting in a
use-after-free.
Add an err_io_stop label that calls hid_device_io_stop() before
hid_hw_close(), and point the two post-io_start error paths at it.
