MdeModulePkg: When media_change happens at Partition.Start(), the lower driver (ScsiDisk) should immediately return EFI_MEDIA_CHANGE but not EFI_SUCCESS. This way is used to avoid the interrupted Partition.Start() closes those opened protocols(DiskIo and DevicePath protocol) who are using by the re-entered partition driver at the same handle.
