commit d8ec26d7f8287f5788a494f56e8814210f0e64be upstream
a27fbf2f067b0cd ("mmc: add ignorance case for CMD13 CRC error") produced
a cmd.flags unhandled in realtek pci host driver. This will make MMC
card fail to initialize, this patch is used to handle the new cmd.flags
condition and MMC card can be used.
