Subject: [PATCH] mmc: sdhci: set to INT_DATA_END when there are data

There is no data, it doesn't needs to wait for completing data transfer.
(It seems that it can be removed.)
Almost all timeout error is occured from stop command without data.
After applied this patch, I hope that we don't need to increase timeout value anymore.
