mmc: rtsx_usb_sdmmc: Avoid keeping the device runtime resumed when unused
commit 31cf742f515c275d22843c4c756e048d2b6d716c upstream.
The rtsx_usb_sdmmc driver may bail out in its ->set_ios() callback when no
SD card is inserted. This is wrong, as it could cause the device to remain
runtime resumed when it's unused. Fix this behaviour.
