mmc: sdio: avoid spurious calls to interrupt handlers
Commit 06e8935feb ("optimized SDIO IRQ handling for single irq") introduced some spurious calls to SDIO function interrupt handlers, such as when the SDIO IRQ thread is started, or the safety check performed upon a system resume. Let's add a flag to perform the optimization only when a real interrupt is signaled by the host driver and we know there is no point confirming it.
