MdeModulePkg/UsbMass: Revert "map -r" media change detection fix
This reverts commit a662afb5b023a187ef638d3cb0e0c313ad39a7fc. * MdeModulePkg/UsbStorage: Fix "map -r" cannot detect media change The above commit fixed the following issue: When system boots to Shell without CDROM inside USB CDROM drive, and then user inserts the CDROM with Eltorito file system, "map -r" cannot show the new ELtorito file system. The commit caused EFI_MEDIA_CHANGED status returned from UsbBootDetectMedia(). But that fix exposes another issue: When issuing ReadCapacity command to certain USB key (Kingston DataTraveler G3 8GB) after it's hot-plugged, USB device returns STALL error and RequestSense command returns media changed sense data. (Most of the USB keys return SUCCESS for ReadCapacity command after hot-plug.)
