mmc: davinci: Handle optional IRQ return value correctly

host->sdio_irq is assigned from platform_get_irq_optional(), which returns a positive IRQ number on success or a negative error code on failure. Therefore, 0 is not a possible return value from this API. Check for a positive IRQ number before requesting the SDIO IRQ instead of treating zero as a valid IRQ.
