SDMMC: guarantee stop-abort cmd in data errors
In error cases, DTO interrupt may or may not be generated depending
    on remained data. Stop/Abort command ensures DTO generation for that
    situation. Currently if 'stop' field of data is empty, there is no
    stop/abort command. So, it could hang waiting DTO. This change
    reinforces these cases.
