mmc: core: Return SD card status if sdr104_wa is not present



On the targets in which sdr104 workaround is not needed, we simply
return card status from mmc_recovery_fallback_lower_speed() call.
This is to fix the issue that are observed with SD card tray holder.
(1b6281740: mmc: core: Return card status if sdr104_wa is not present)

Since this change is meant to fix issue observed with SD card tray
holder, for other devices(eMMC/SDIO) we should ignore this.
