mmc: dw_mmc: fix the transfer termination in IDMAC mode

In IDMAC mode EVENT_XFER_COMPLETE is set when RI/TI of last descriptor is done. So if errors are happened in the middle of data transfers, 'dw_mci_stop_dma' during error handing can be called and eventually prevents this flag to be set.
This results in permanent wait for EVENT_XFER_COMPLETE in 'dw_mci_tasklet_func'. Therefore, if dma running is stopped forcibly, EVENT_XFER_COMPLETE should be set.
