mmc: core: Prevent processing SDIO IRQs when the card is suspended
Processing of SDIO IRQs must obviously be prevented while the card is system suspended, otherwise we may end up trying to communicate with an uninitialized SDIO card. Reports throughout the years shows that this is not only a theoretical problem, but a real issue. So, let's finally fix this problem, by keeping track of the state for the card and bail out before processing the SDIO IRQ, in case the card is suspended.
