mmc: dw_mmc: fix error handling in PIO mode
Data transfer will be continued until all the bytes are transmitted, even if data crc error occurs during a multiple-block data transfer. This means RXDR/TXDR interrupts will occurs until data transfer is terminated. Early setting of host->sg to NULL prevents going into xxx_data_pio functions, hence permanent unhandled RXDR/TXDR interrupts occurs. And checking error interrupt status in the xxx_data_pio functions is no need because dw_mci_interrupt does do the same. This patch also removes it.
