Add new ack interrupt API to avoid using VFIO_IRQ_SET_ACTION_TRIGGER(rte_intr_enable()) for acking interrupt purpose for VFIO based interrupt handlers. This implementation is specific to Linux. Using rte_intr_enable() for acking interrupt has below issues * Time consuming to do for every interrupt received as it will free_irq() followed by request_irq() and all other initializations * A race condition because of a window between free_irq() and request_irq() with packet reception still on and device still enabled and would throw warning messages like below. [158764.159833] do_IRQ: 9.34 No irq handler for vector In this patch, rte_intr_ack() is a no-op for VFIO_MSIX/VFIO_MSI interrupts as they are edge triggered and kernel would not mask the interrupt before delivering the event to userspace and we don't need to ack.
