mmc: try low speed fallback only for sd card
In _mmc_detect_card_removed() when alive check shows removed card,
it want to give 2nd chance to fallback to low speed to see if it can
become live again. But mmc_recovery_fallback_lower_speed() only apply
to sd card. In case of sdio card, mmc_recovery_fallback_lower_speed()
simply return 0, which will overwrite the previous checked alive state.
Check card type before call mmc_recovery_fallback_lower_speed function.
