fixed a condition where device issues a status cmd to sdcard but no response
comes from sdcard. The sdhci irq fires and we hit a timeout case which calls
sdhci_finish_data(). sdhci_finish_data eventually attempt to reset controller
and issues stop cmd. However mmcdq is wait_for_completion(&mrq->completion)
in function mmc_wait_for_req_done which never occurs.
