sdio: kick the interrupt thread upon a resume 



Some SDIO cards may suspend while keeping function interrupts active
especially in the powered suspend case.  Upon resume we need to kick the
SDIO interrupt thread to check for pending interrupts and to restart card
IRQ detection at the host controller level.
