[ Upstream commit db6341a9168d2a24ded526277eeab29724d76e9d ]
Traditional utcl2 fault_status polling does not work in SRIOV environment. The polling of fault status register from guest side will be dropped by hardware.
Driver should switch to check utcl2 interrupt source id to identify utcl2 poison event. It is set to 1 when poisoned data interrupts are signaled.
v2: drop the unused local variable (Tao)
