mmc: sdhci: Clear pointers when a request finishes
Several pointers are used to identify when interrupts are expected. Namely, host->cmd, host->data_cmd and host->data. Ensure those are cleared when a request finishes. That tidies the case when a request is errored out before normal processing has completed, ensuring any interrupts that occur subsequently are not acted upon.
