mmc: rtsx: fix possible linking error if built-in

rtsx_usb_sdmmc module uses the LED classdev if available, but the code failed to consider the situation that it is built-in and the LED classdev is a module, leading to following linking error:

LD init/built-in.o
drivers/built-in.o: In function `rtsx_usb_sdmmc_drv_remove':
rtsx_usb_sdmmc.c:(.text+0x2a018e): undefined reference to `led_classdev_unregister'
drivers/built-in.o: In function `rtsx_usb_sdmmc_drv_probe':
rtsx_usb_sdmmc.c:(.text+0x2a197e): undefined reference to `led_classdev_register'

Fix by excluding such condition when defining macro RTSX_USB_USE_LEDS_CLASS.

v2 by Arnd: change the second #ifdef as well.
