Subject: [PATCH] mmc: sdhci: Avoid needless loop while handling SDIO
 interrupts in sdhci_irq

Ignore Card Interrupt bit in the interrupt status if we already
know that mmc_signal_sdio_irq() is going to be called at the end of
sdhci_irq(). This avoids a needless loop in sdhci_irq() repeatedly
reading interrupt status and doing nothing.
