mmc: msm_sdcc: Check for only DATA_END interrupt to end a request

Browse Source 
The current code checks for both DATA_END and DATA_BLK_END bits in
MCI_STATUS register and ends a request only if both are set at a time.
The hardware doesn't always set DATA_BLK_END when DATA_END is set.
But DATA_END status itself is sufficient condition from hardware that
data transfer is done and hence, check for only DATA_END interrupt in
software to end a request.
