Realtek card reader supports both SD and MS card. According to the settings of rtsx MFD driver, SD host will be probed before MS host. If we boot/reboot Linux with SD card inserted, the resetting flow of SD card will succeed, and the following resetting flow of MS is sure to fail. Then MS upper-level driver will ask rtsx driver to turn power off. This request leads to the result that the following SD commands fail and SD card can't be accessed again. In this commit, Realtek's SD and MS host driver will check whether the card that upper driver requesting is the one existing in the slot. If not, Realtek's host driver will refuse the operation to make sure the exlusive accessing at the same time.
