Revert "ARM: 7220/1: mmc: mmci: Fixup error handling for dma"

This reverts commit c8cdf3f97d34d906e0519d5cbc2ab3f81269d0b4, applied on
linux 2.6.32.53 stable release, as it can introduce the following build
error while building 2.6.32.y on armel:

linux-2.6.32/drivers/mmc/host/mmci.c: In function 'mmci_cmd_irq':
linux-2.6.32/drivers/mmc/host/mmci.c:237: error: implicit declaration of function 'dma_inprogress'
linux-2.6.32/drivers/mmc/host/mmci.c:238: error: implicit declaration of function 'mmci_dma_data_error'

Aparently the commit was wrongly pushed into 2.6.32, since it depends on
commit c8ebae37 ("ARM: mmci: add dmaengine-based DMA support"), not
present on 2.6.32.
